Maven配置SpringMVC4+Spring4+Mybatis3环境

一、添加依赖

1、新建maven的web项目后，在pom.xml添加依赖信息，对应的groupId 、artifactId修改成自己新建的

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>web-ssm</groupId><artifactId>whymoy</artifactId><packaging>war</packaging><version>1.0-SNAPSHOT</version><name>whymoy Maven Webapp</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><springVersion>4.3.0.RELEASE</springVersion><jacksonVersion>2.9.3</jacksonVersion><mybatisVersion>3.4.4</mybatisVersion><mybatisSpringVersion>1.3.0</mybatisSpringVersion><c3p0Version>0.9.5.2</c3p0Version><mysqlVersion>5.1.38</mysqlVersion><slf4jVersion>1.7.21</slf4jVersion><log4jVersion>1.2.17</log4jVersion><jstlVersion>1.2</jstlVersion><servletApiVersion>3.1.0</servletApiVersion><junitVersion>4.12</junitVersion></properties><dependencies><!--junit 测试开始--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junitVersion}</version><scope>test</scope></dependency><!--junit 测试结束--><!--Slf4j + Log4j日志依赖 开始--><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4jVersion}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4jVersion}</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4jVersion}</version></dependency><!--Slf4j + Log4j日志依赖 结束--><!--JavaEE web容器提供 开始--><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>${servletApiVersion}</version><scope>provided</scope></dependency><!--JavaEE web容器提供 开始--><!--Jsp 常用标签库依赖 开始--><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>${jstlVersion}</version><scope>runtime</scope></dependency><!--Jsp 常用标签库依赖 结束--><!-- SpringMVC模块依赖 开始--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${springVersion}</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>${jacksonVersion}</version></dependency><!-- SpringMVC模块依赖 结束--><!-- Mybatis模块依赖 开始--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatisVersion}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatisSpringVersion}</version></dependency><!-- Mybatis模块依赖 结束--><!--C3p0 数据库连接池依赖 开始--><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>${c3p0Version}</version></dependency><!--C3p0 数据库连接池依赖 结束--><!--Jdbc 驱动依赖 开始 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysqlVersion}</version></dependency><!--Jdbc 驱动依赖 结束 --><!--Spring常用模块依赖 开始--><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${springVersion}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${springVersion}</version></dependency><!--Spring常用模块依赖结束--></dependencies><build><finalName>whymoy</finalName><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.8</source><target>1.8</target></configuration></plugin><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><port>8080</port><charset>${project.build.sourceEncoding}</charset><server>tomcat7</server></configuration></plugin></plugins></build>

2、个人使用的数据库是mysql，需要新建数据库whymoy，初始化sql语句

CREATE TABLE t_test (id int(11) NOT NULL AUTO_INCREMENT,description varchar(255) DEFAULT NULL,gtm_create datetime DEFAULT NULL,gtm_modified datetime DEFAULT NULL,PRIMARY KEY (id)
)

View Code

3、个人的项目信息结构

二、添加配置信息

1、在修改web.xml信息

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version="3.1"><!-- *** 初始化Spring容器开始 *** --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><!-- === 初始化Spring容器结束 === --><!-- *** 初始化SpringMVC开始 *** --><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-mvc.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><!-- === 初始化SpringMVC结束 === -->
</web-app>

View Code

2、在classpath下添加spring.xml文件，base-package属性值可以改成自己对应的项目基础包名

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><context:component-scan base-package="com.moy" /><import resource="spring-mvc.xml"/><import resource="spring-dao.xml"/><import resource="spring-tx.xml"/><import resource="spring-task.xml"/>
</beans>

View Code

3、在classpath下添加spring-dao.xml，添加数据源配置，packagesToScan列出来的实体类包名可以换成自己的

<?xml version="1.0" encoding="UTF-8"?>
