java中SSM环境搭建

SSM环境搭建过程

mybatis,spring,SpringMVC三大框架整合(idea工具）

1、引入依赖

<dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-expression</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jcl</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.1.4.RELEASE</version></dependency><dependency><groupId>aopalliance</groupId><artifactId>aopalliance</artifactId><version>1.0</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.9.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version></dependency><dependency><groupId>asm</groupId><artifactId>asm</artifactId><version>3.3.1</version></dependency><dependency><groupId>cglib</groupId><artifactId>cglib</artifactId><version>2.2.2</version></dependency><dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>3.17.1-GA</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.7</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>1.7.5</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.5</version><scope>test</scope></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.2</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.6</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.12</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.1.1</version></dependency><dependency><groupId>taglibs</groupId><artifactId>standard</artifactId><version>1.1.1</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.8</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.9.8</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-annotations</artifactId><version>2.9.8</version></dependency><!--文件上传依赖--><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.3</version></dependency></dependencies>
<!--绑定资源目录--></pluginManagement><resources><resource><directory>src/main/java</directory><includes><include>**/*.xml</include><include>**/*.properties</include></includes></resource><resource><directory>src/main/resources</directory><includes><include>**/*.xml</include><include>**/*.properties</include></includes></resource></resources></build>
</project>

数据库建立

数据库：
SET FOREIGN_KEY_CHECKS=0;

 -- ------------------------------ Table structure for employee-- ----------------------------DROP TABLE IF EXISTS `employee`;CREATE TABLE `employee` (`empid` int(11) NOT NULL AUTO_INCREMENT,`empName` varchar(50) DEFAULT NULL,`partment` varchar(50) DEFAULT NULL,`picture` varchar(50) DEFAULT NULL,`state` varchar(50) DEFAULT NULL,PRIMARY KEY (`empid`)) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;-- ------------------------------ Records of employee-- ----------------------------INSERT INTO `employee` VALUES ('1', '张三', '1', 'logo.jpg', '离职');INSERT INTO `employee` VALUES ('2', '李四', '2', 'bieshu.png', '离职');INSERT INTO `employee` VALUES ('6', '王五', '2', 'zs.png', '在职');INSERT INTO `employee` VALUES ('10', 'cc', '1', 'cc.jpg', '在职');INSERT INTO `employee` VALUES ('11', '', '1', '308f94e3-8aa7-4c44-889a-e206e7f48550_c#.txt', '在职');

2、配置文件目录

3、建立配置文件

3.1 建立jdbc.properties

jdbc.dr=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///test?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf8
jdbc.username=root(自己数据库账户)
jdbc.password=自己数据库密码

3.2 新建mybatis.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><!--为实体类指定别名 自己指定自己包名--><typeAliases><package name="com.xxx.entity"/></typeAliases><!--注册映射文件 自己指定自己的dao层映射文件--><mappers><package name="com.xxx.**.dao"/></mappers>
</configuration>

3.3 新建spring-ds.xml

    <!--注入db.properties--><context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"><property name="driverClassName" value="${jdbc.dr}"></property><property name="url" value="${jdbc.url}"></property><property name="username" value="${jdbc.username}"></property><property name="password" value="${jdbc.password}"></property></bean>

3.4新建spring-mvc.xml

 <!--注册组件扫描器，扫描@Controller--><context:component-scan base-package="com.aynu.**.controller"/><!--MVC注解驱动--><mvc:annotation-driven/><!--配置登录拦截器--><mvc:interceptors><mvc:interceptor><mvc:mapping path="/**"/><bean class="com.hrm.filter.LoginInterceptor"/></mvc:interceptor></mvc:interceptors><!--文件解析器--><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="maxUploadSize" value="104857600" /><property name="maxInMemorySize" value="4096" /></bean>

3.5 spring-mybatis.xml,spring整合mybatis

<!--生成sqlSessionFactory--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="configLocation" value="classpath:mybatis.xml"/></bean><!--生成dao接口的动态代理--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.aynu.**.dao"/><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/></bean>

3.6 把service注入到spring,新建spring-service.xml

<!--注册组件扫描器，扫描@Service--><context:component-scan base-package="com.aynu.**.service"/>

3.7 注册事务管理器，新建spring-tx.xml

<!--注册平台事务管理器--><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean><!--事务通知--><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="find*" isolation="DEFAULT" propagation="REQUIRED"/><tx:method name="add*" isolation="DEFAULT" propagation="REQUIRED"/><tx:method name="modify*" isolation="DEFAULT" propagation="REQUIRED"/><tx:method name="remove*" isolation="DEFAULT" propagation="REQUIRED"/></tx:attributes></tx:advice><!--AOP切面配置--><aop:config><aop:pointcut id="myPC" expression="execution(* *..service.*.*(..))"/><aop:advisor advice-ref="txAdvice" pointcut-ref="myPC"/></aop:config>

4、web.xml配置

<!--注册中央调度器--><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-*.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><!--编码过滤器--><filter><filter-name>encodinFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodinFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--登录验证过滤器--><!--<filter><filter-name>loginFilter</filter-name><filter-class>com.hrm.filter.LoginFilter</filter-class></filter><filter-mapping><filter-name>loginFilter</filter-name><url-pattern>*.jsp</url-pattern><url-pattern>*.do</url-pattern></filter-mapping>-->

5、过滤器(拦截器过滤器任选其一，我首选过滤器)

目的和作用：
防止用户越过登陆验证，直接输入地址进行操作。要想使用该网站，必须拦截登陆请求

/*
* 采用过滤器拦截越域用户
* 方法：通过获取session域中是否存在对象
* */
public class MyLoginFilter implements Filter {//此处应该放掉登陆界面和登陆的处理器private  String[] need_uri = {"/index.jsp","/loginForm.jsp","/login.do"};@Overridepublic void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {//index.jsp,loginForm.jsp,login.do放掉这三个HttpServletRequest request = (HttpServletRequest) servletRequest;HttpServletResponse response = (HttpServletResponse) servletResponse;//获取每次的请求路径String strURI = request.getRequestURI();//循环查看请求地址是否包含上三个boolean flag = false;for (String str : need_uri) {//如果包含，即已经登陆；防止空指针异常if (strURI.contains(str)) {//放行flag = true;filterChain.doFilter(request, response);break;}}if (!flag) {//不包含 拦截User login_user = (User) request.getSession().getAttribute("loginUser");if (login_user != null) {filterChain.doFilter(request, response);} else {request.setAttribute("login_error", "你还未登陆请登陆");//请求转发request.getRequestDispatcher("/index.jsp").forward(request, response);}}}
}

6.拦截器

public class LoginInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {String requestURI = request.getRequestURI();if (requestURI.endsWith("/login.do")){return true;}User login_user = (User) request.getSession().getAttribute("login_user");if (login_user != null){return true;}else {request.setAttribute("login_error","您还未登录，请登录后访问！");request.getRequestDispatcher("/index.jsp").forward(request,response);return false;}}
}

7、用户登陆和注销操作

@RequestMapping("/login.do")public String login(User user, HttpSession session, Model model){//System.out.println(user);User login_user = userService.findUserByLoginnameAndPassword(user);//System.out.println(login_user);if (login_user != null){session.setAttribute("login_user",login_user);return "/jsp/main.jsp";}else {model.addAttribute("login_error","用户名或密码不正确，请重新输入！");return "/index.jsp";}}@RequestMapping("/logout.do")public String logout(HttpSession session,Model model){session.removeAttribute("login_user");model.addAttribute("login_error","退出成功，请重新登录！");return "/index.jsp";}

8、代码层建立

三层架构环境搭建： entity实体类：实体类：@Datapublic class Employee {private Integer empid;private String empName;private Integer partment;private String picture;private String state;}dao包：dao接口：public interface EmployeeDao {List<Employee> selectAllEmployees();}dao.xml<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.xja.ssm.dao.EmployeeDao"><select id="selectAllEmployees" resultType="Employee">select * from employee</select></mapper>service层：servicepublic interface EmployeeService {List<Employee> findAllEmployees();}serviceImpl:@Servicepublic class EmployeeServiceImpl implements EmployeeService {@Resourceprivate EmployeeDao employeeDao;@Overridepublic List<Employee> findAllEmployees() {return employeeDao.selectAllEmployees();}}controller层：@Controllerpublic class EmployeeController {@Autowiredprivate EmployeeService employeeService;@RequestMapping("/findAllEmp.do")public String findAllEmp(Model model){List<Employee> employeeList = employeeService.findAllEmployees();model.addAttribute("emps",employeeList);for(Employee emp:employeeList) {System.out.println(emp);}return "index.jsp";}}index.jsp:<a href="/findAllEmp.do">查看所有的员工</a><br>${emps}
