项目主要结构：

1.创建maven项目选maven-archetype–webapp骨架

mysql数据库文件

/*

3.完善工程的包的结构
1.）创建一个 java文件夹----改文件夹的状态（java选source，资源的选resource，测试的选test）
2.）在文件夹下建包，包下创建具体的包—–实体层pojo,业务层service,持久层repository（dao层），控制层controller。（如文章顶部项目主要结构的图）
3.）下面图为注意事项：

4.resource文件夹下写几个配置文件-------spring.xml，springmvc.xml，数据库连接的jdbc.properties

注意：易错点--------(有的时候出错，实在查不出来时看看这个)jdbc.properties里开头加前缀jdbc。不加前缀，在获取用户名的时候（数据库连接用户名）有可能获得计算机的名。此处代码如下图，自己动手吧！
以下正式配置
1.)首先配置spring.xml(代码在下方)
配置包扫描
注意：spring要扫描service（业务层）层，springmvc扫描controller 层，mybatis扫描dao层，需要被扫描的类要增加组件注解，例如 @Controller。
Spring.xml-------------首先增加命名空间及约束
再<!-配置包的扫描–>

命名空间对应的映射约束添加后就可以扫描了

注意：有映射文件mapper，.xml也扫描不了，因为java文件是蓝色的（资源文件），其只能识别 .java文件。Mapper文件下的 .xml文件识别不了，在pom.xml里配置排除操作

添加排除配置

pom.xml添加排除配置代码（在pom.xml的build标签下添加）

<resources><resource><directory>${basedir}/src/main/java</directory><includes><include>**/*.xml</include></includes></resource>
</resources>

spring.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><!--包扫描--><context:component-scan base-package="com.pb.ssm.service"/><!--引入数据库连接文件--><context:property-placeholder location="classpath:jdbc.properties"/><!--注入数据源--><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"><property name="password" value="${jdbc.password}"/><property name="username" value="${jdbc.username}"/><property name="url" value="${jdbc.url}"/><property name="driverClassName" value="${jdbc.driver}"/></bean><!--整合mybatis-spring--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><!--定义别名--><property name="typeAliasesPackage" value="com.pb.ssm.pojo"/><!--扫描sql映射文件--><property name="mapperLocations" value="classpath:com/pb/ssm/mapper/*.xml"/><!--添加插件--><property name="plugins"><array><!--添加的mybatis分页插件--><bean class="com.github.pagehelper.PageInterceptor"><property name="properties"><value>param1=mysql</value></property></bean></array></property></bean><!--注入(扫描)dao接口（即repository）--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.pb.ssm.repository"/><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/></bean>
</beans>

2.)完善pojo—创建Brand实体类属性，set /get/ to string()

package com.pb.ssm.pojo;import java.util.Date;/*** @ClassName Brand* @Description TODO* @Author david* @Date 2019/02/15 14:37* @Version 1.0*/
public class Brand {private Long id;private Date createDate;private Date modifyDate;private String chineseName;private String englishName;private String desc;private String logo;private Integer type;private String url;private String story;private Integer status;public Long getId() {return id;}public void setId(Long id) {this.id = id;}public Date getCreateDate() {return createDate;}public void setCreateDate(Date createDate) {this.createDate = createDate;}public Date getModifyDate() {return modifyDate;}public void setModifyDate(Date modifyDate) {this.modifyDate = modifyDate;}public String getChineseName() {return chineseName;}public void setChineseName(String chineseName) {this.chineseName = chineseName;}public String getEnglishName() {return englishName;}public void setEnglishName(String englishName) {this.englishName = englishName;}public String getDesc() {return desc;}public void setDesc(String desc) {this.desc = desc;}public String getLogo() {return logo;}public void setLogo(String logo) {this.logo = logo;}public Integer getType() {return type;}public void setType(Integer type) {this.type = type;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getStory() {return story;}public void setStory(String story) {this.story = story;}public Integer getStatus() {return status;}public void setStatus(Integer status) {this.status = status;}@Overridepublic String toString() {return "brand{" +"id=" + id +", createDate=" + createDate +", modifyDate=" + modifyDate +", chineseName='" + chineseName + '\'' +", englishName='" + englishName + '\'' +", desc='" + desc + '\'' +", logo='" + logo + '\'' +", type=" + type +", url='" + url + '\'' +", story='" + story + '\'' +", status=" + status +'}';}
}

3.)完善持久层repository（dao层接口）

import org.apache.ibatis.annotations.Param;import java.util.List;/*** @ClassName BrandRepository* @Description TODO* @Author david* @Date 2019/02/15 16:00* @Version 1.0*/
public interface BrandRepository {//（jsp查找里，及list列表用）List<Brand> findBrandByName(@Param("chineseName") String name);//查看Brand findBrandById(@Param("id") Integer id);//删除，返回影响个数int deleteById(@Param("id") Integer id);
}

4.)完善mapper文件下的映射文件

进入BrandRepository后Alt+回车生成方法体（问题点：自己的没有生成，idea版本问题）

生成的样式如下（自己的没实现，可以直接建这个文件）

mapper文件下的BrandRepository.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.pb.ssm.repository.BrandRepository"><sql id="allColoum">id,createDate,modifyDate,chineseName,englishName,`desc`,logo,`type`,url,story,status</sql><select id="findBrandByName" resultType="com.pb.ssm.pojo.Brand">select <include refid="allColoum"/>FROM b_brand<where><if test="chineseName!=null and chineseName!=''">chineseName LIKE CONCAT('%',#{chineseName},'%')</if></where>
/*查出的排序*/order by modifyDate desc</select><!--查找--><select id="findBrandById" resultType="com.pb.ssm.pojo.Brand">SELECT<include refid="allColoum"/>FROM b_brandWHERE id=#{id}</select><!--删除--><delete id="deleteById">DELETE  FROM b_brand where id=#{id}</delete>
</mapper>

5.)完善service(业务层)—建一个接口BrandService ----Alt+回车生成impl

BrandService代码

package com.pb.ssm.service;import com.github.pagehelper.PageInfo;
import com.pb.ssm.pojo.Brand;import java.util.List;/*** @ClassName BrandService* @Description TODO* @Author david* @Date 2019/02/15 21:38* @Version 1.0*/
public interface BrandService {List<Brand> findBrandByName(String chineseName);PageInfo<Brand> findBrandPageByName(String chineseName,Integer pageNum,Integer pageSize);Brand findBrandById(Integer id);boolean deleteById(Integer id);
}

BrandServiceImpl代码

package com.pb.ssm.service.impl;import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.pb.ssm.pojo.Brand;
import com.pb.ssm.repository.BrandRepository;
import com.pb.ssm.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;/*** @ClassName BrandServiceImpl* @Description TODO* @Author david* @Date 2019/02/15 22:08* @Version 1.0*/
@Service
public class BrandServiceImpl implements BrandService {@Autowiredprivate BrandRepository brandRepository;@Overridepublic List<Brand> findBrandByName(String chineseName) {return brandRepository.findBrandByName(chineseName);}@Overridepublic PageInfo<Brand> findBrandPageByName(String chineseName, Integer pageNum, Integer pageSize) {PageHelper.startPage(pageNum,pageSize);List<Brand> brands = brandRepository.findBrandByName(chineseName);PageInfo<Brand> brandPageInfo=new PageInfo<>();brandPageInfo.setList(brands);return brandPageInfo;}@Overridepublic Brand findBrandById(Integer id) {return brandRepository.findBrandById(id);}@Overridepublic boolean deleteById(Integer id) {if(brandRepository.deleteById(id)>0){return true;}return false;}
}

6.)在BrandSerciceImpl类，生成test测试类

package com.pb.ssm.service.impl;import com.github.pagehelper.PageInfo;
import com.pb.ssm.pojo.Brand;
import com.pb.ssm.service.BrandService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import java.util.List;import static org.junit.Assert.*;/*** @ClassName BrandServiceImplTest* @Description TODO* @Author david* @Date 2019/02/15 22:09* @Version 1.0*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring.xml")
public class BrandServiceImplTest {
//    注入业务层@Autowiredprivate BrandService brandService;@Testpublic void findBrandByName() throws Exception{List<Brand> brands=brandService.findBrandByName("三");System.out.println(brands);System.out.println(brands.size());}

7.)配置springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><!--包扫描--><context:component-scan base-package="com.pb.ssm.controller"/><!--注解驱动--><mvc:annotation-driven/><mvc:default-servlet-handler/><!--视图解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp"/><property name="suffix" value=".jsp"/></bean>
</beans>

8.)再创建list.jsp (运行jsp需要tommcat)

把build下面的那个上移

list.jsp代码

</div>
</div>
</body>
</html>

9.)完善controller

在这package com.pb.ssm.controller;import com.pb.ssm.pojo.Brand;
import com.pb.ssm.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.*;import javax.servlet.http.HttpServletRequest;
import java.util.List;/*** @ClassName BrandController* @Description TODO* @Author david* @Date 2019/02/15 22:45* @Version 1.0*///@RestController
@Controller     //加前台页面用controller,不用RestController
@RequestMapping("/admin/brand")
public class BrandController {@Autowiredprivate BrandService brandService;@GetMapping("/list")  //chineseName有可能为空，为避免，用@RequestParam("chineseName")public String list(@RequestParam(value = "chineseName",required = false)String chineseName , ModelMap model){//value = "chineseName"这个参数也可以不用传，在查询所有时不用传参，HttpServletRequest还得各种判断，麻烦List<Brand> brands=brandService.findBrandByName(chineseName);model.addAttribute("brans",brands);model.addAttribute("size",brands.size());//视图解析器--springmvc.xml内 <property name="prefix" value="/WEB-INF/jsp"/>//接jsp后的/return "/admin/brand/list";}@GetMapping("/view/{id}")public String view(@PathVariable("id") String id, ModelMap model){//controller里根本不写if else，只是调业务层的东西Integer finallId=0;if(id!=null){finallId=Integer.valueOf(id);}Brand brand=brandService.findBrandById(finallId);model.addAttribute("brand",brand);//重定向return "/admin/brand/view";}@GetMapping("/delete/{id}")public String  delete(@PathVariable("id")String id){Integer finallId=0;if(id!=null){finallId=Integer.valueOf(id);}boolean result=brandService.deleteById(finallId);//简单些写的，正常是有判断的，错误的跳转到error页面return "redirect:/admin/brand/list";}}

10.)完善web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>Archetype Created Web Application</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><!--配置spring监听器 作用：可以监听spring的上下文文件（context），注意顺序--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--spring字符编码过滤器start--><filter><!--①spring编码过滤器--><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><!--②编码方式--><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><!--③强制进行编码转换--><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><!--过滤器的匹配URL--><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--配置springMVC,其底层是servlet，所以servlet-name--><servlet><servlet-name>springMVC</servlet-name><!--核心前端控制器--><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!--初始化参数--><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><!--参数启动顺序，1是第二个启动--><load-on-startup>1</load-on-startup></servlet><!--映射，根目录下所有的东西都走核心前端控制器，由它管理--><servlet-mapping><servlet-name>springMVC</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
</web-app>

11.)启动tommcat(注意网址)
，有时候会在localhost：8080/后面出现含_war_的地址，在后续的运行查看view，删除操作时，接着网址后面直接写网址（如8080/…war…/admin/brand/view）.正常时候直接localhost：8080/admin/brand/view

注意：List.jsp里加下面2个在线引用（或在js文件夹下导入jar包），可以使用bootstrap的在线工具写jsp

<%--Bootstrap 3.0.3 js 文件--%>
<script src="http://libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script>
<%--Bootstrap 3.0.3 css 文件--%>
<link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet" />

jsp里的搜索（查找） ------注意中文乱码问题(在web.xml里加过滤器没起作用，其他未调试，检索英文没问题，可以试一下数据库内的数据，下面会添加文件)

类似如下

查看功能实现（文章上面代码块里有的已经复制了）

写repository文件下的BrandRepository接口下的查看接口
Brand findBrandById(@Param(“id”) Integer id);
(可快捷键生成方法体，自己idea版本不行)，生成mapper文件下的BrandRepository.xml里的方法体

<!--查找-->
<select id="findBrandById" resultType="com.pb.ssm.pojo.Brand">SELECT<include refid="allColoum"/>FROM b_brandWHERE id=#{id}
</select>

业务层service下的BrandService接口
Brand findBrandById(Integer id);
业务层service包下impl包下的BrandServiceImpl接口（里面的内容全都复制下了）

@Service
public class BrandServiceImpl implements BrandService {@Autowiredprivate BrandRepository brandRepository;@Overridepublic List<Brand> findBrandByName(String chineseName) {return brandRepository.findBrandByName(chineseName);}
//查询用到的@Overridepublic Brand findBrandById(Integer id) {return brandRepository.findBrandById(id);}@Overridepublic boolean deleteById(Integer id) {if(brandRepository.deleteById(id)>0){return true;}return false;}

控制层Controller包下的BrandController类

@GetMapping("/view/{id}")public String view(@PathVariable("id") String id, ModelMap model){//controller里根本不写if else，只是调业务层的东西Integer finallId=0;if(id!=null){finallId=Integer.valueOf(id);}Brand brand=brandService.findBrandById(finallId);model.addAttribute("brand",brand);//重定向return "/admin/brand/view";
}

创建view.jsp页面
（注意list.jsp内的href地址）页面传id后，才能知道跳转到什么地方。(rest风格传递)

</div>
</body>
</html>

删除操作代码—同上

分页：（分页代码，上文的代码块有些已经涵盖，自己再看一下）
1.Spring.xml里spring整合mybatis时增加一个插件

<!--添加插件-->
<property name="plugins"><array><!--添加的mybatis分页插件--><bean class="com.github.pagehelper.PageInterceptor"><property name="properties"><value>param1=mysql</value></property></bean></array>
</property>

2.Pom.xml里增加的：

<!--mybatis分页-->
<dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId><version>5.1.2</version>
</dependency>
<dependency><groupId>com.github.jsqlparser</groupId><artifactId>jsqlparser</artifactId><version>0.9.7</version>
</dependency>

3.service包下Brandservice加接口

PageInfo<Brand> findBrandPageByName(String chineseName,Integer pageNum,Integer pageSize);

实现BrandserviceImpl

@Override
public PageInfo<Brand> findBrandPageByName(String chineseName, Integer pageNum, Integer pageSize) {PageHelper.startPage(pageNum,pageSize);List<Brand> brands = brandRepository.findBrandByName(chineseName);PageInfo<Brand> brandPageInfo=new PageInfo<>();brandPageInfo.setList(brands);return brandPageInfo;
}

4.进行impl测试，生成test类

@Test
public void findBrandPageByName() {PageInfo<Brand> brandPageByName = brandService.findBrandPageByName(null, 1, 2);for (Brand b:brandPageByName.getList()) {System.out.println(b);}
}

5.）运行测试文件

运行日志里有红框内的内容，分页配置成功。注：分页页面未写，自己看着添加一个更好
