maven工程分模块项目可以模块与模块之间的耦合度降低，各模块之间的联系就没有那么的紧密。通常情况下为了打包方便，建立一个父类的模块。这样打包发布的时候就不用一个个模块打包过去，只有父类的模块手动打包下就可以了，
工程如下图所示：
其中book-parent为父类模块，book-core持久层，book-service为服务层，book-web的可视化层 ，既分别对应mvc中的相应层。
一、book-core
1、添加包支持，pom.xml配置如下：
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>book-core</artifactId> <packaging>jar</packaging> <parent> <groupId>com.myWebApp</groupId> <artifactId>book-parent</artifactId> <version>0.0.1-SNAPSHOT</version> <relativePath>../book-parent/pom.xml</relativePath> </parent> <name>book-core</name> <!--由于使用父类因此配置如下--> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> </dependency> <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </dependency> <dependency> <groupId>javax.persistence</groupId> <artifactId>persistence-api</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </build> </project>
父类pom.xml配置如下：

注意：有些包是多余的，
2、实体类User代码如下：
package com.mr.cheng.entity;
public class User {
private Integer id;
private String descn;
private String username;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getDescn() {
return descn;
}
public void setDescn(String descn) {
this.descn = descn == null ? null : descn.trim();
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username == null ? null : username.trim();
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password == null ? null : password.trim();
}
}
3、User实体类对已的Dao与xml文件代码如下：
<?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.mr.cheng.dao.IUserDao" >
<resultMap id="BaseResultMap" type="com.mr.cheng.entity.User" >
<id column="Id" property="id" jdbcType="INTEGER" />
<result column="descn" property="descn" jdbcType="VARCHAR" />
<result column="username" property="username" jdbcType="VARCHAR" />
<result column="password" property="password" jdbcType="VARCHAR" />
</resultMap>
<delete id="deleteByPrimaryKey" parameterType="java.lang.Integer" >
delete from users
where Id = #{id,jdbcType=INTEGER}
</delete>
<insert id="insert" parameterType="com.mr.cheng.entity.User" >
insert into users (Id, descn, username,
password)
values (#{id,jdbcType=INTEGER}, #{descn,jdbcType=VARCHAR}, #{username,jdbcType=VARCHAR},
#{password,jdbcType=VARCHAR})
</insert>
<update id="updateByPrimaryKey" parameterType="com.mr.cheng.entity.User" >
update users
set descn = #{descn,jdbcType=VARCHAR},
username = #{username,jdbcType=VARCHAR},
password = #{password,jdbcType=VARCHAR}
where Id = #{id,jdbcType=INTEGER}
</update>
<select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer" >
select Id, descn, username, password
from users
where Id = #{id,jdbcType=INTEGER}
</select>
<select id="selectAll" resultMap="BaseResultMap" >
select Id, descn, username, password
from users
</select>
</mapper>
package com.mr.cheng.dao;
import com.mr.cheng.entity.User;
import java.util.List;
import org.springframework.stereotype.Component;
/**
* 注意注解@Component必须有，也可以用Service或者Controller代替
* @author zwc
*
*/
@Component
public interface IUserDao {
int deleteByPrimaryKey(Integer id);
int insert(User record);
User selectByPrimaryKey(Integer id);
List<User> selectAll();
int updateByPrimaryKey(User user);
}
4、spring-mybatis.xml配置如下：
<?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" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 数据库连接配置 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost:3306/hibernate"></property>
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
<!-- spring集成MyBaits -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
<property name="mapperLocations" value="classpath:com/mr/cheng/xml/*.xml" />
</bean>
<!-- 使dao与xml文件一一对应 ，注意dao接口必须使用注解 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mr.cheng.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
<!-- 添加注解支持 -->
<tx:annotation-driven />
</beans>
5、测试类如下：
package com.mr.cheng.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 com.mr.cheng.dao.IUserDao;
import com.mr.cheng.entity.User;
public class MyAppTest {
@Autowired
private IUserDao iUserDao;
public void addUserTest(){
User user = new User();
user.setDescn("111");
user.setPassword("password");
user.setUsername("cheng");
iUserDao.insert(user);
}
}
二、book-service
1、book-service是服务层，它对外提供接口。控制层不需要知道具体的实现，只有根据相应的接口就可以去选择他要想的服务。
接口代码如下：
package com.mr.cheng.biz; import java.util.List; import org.springframework.stereotype.Component; import com.mr.cheng.entity.User; @Component public interface UserBizDao { int deleteByPrimaryKey(Integer id); int insert(User record); User selectByPrimaryKey(Integer id); List<User> selectAll(); int updateByPrimaryKey(User user); }
实现类：
package com.mr.cheng.biz.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.mr.cheng.biz.UserBizDao; import com.mr.cheng.dao.IUserDao; import com.mr.cheng.entity.User; @Service public class UserBizDaoImpl implements UserBizDao { @Autowired private IUserDao iUserDao; public int deleteByPrimaryKey(Integer id) { iUserDao.deleteByPrimaryKey(id); return 0; } public int insert(User record) { iUserDao.insert(record); return 0; } public User selectByPrimaryKey(Integer id) { return iUserDao.selectByPrimaryKey(id); } public List<User> selectAll() { return iUserDao.selectAll(); } public int updateByPrimaryKey(User user) { iUserDao.updateByPrimaryKey(user); return 0; } }
2、配置文件：
spring-service如下：
<?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" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <tx:annotation-driven /> <context:component-scan base-package="com.mr.cheng.biz.impl.*" /> </beans>
pom.xml代码如下：
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>book-service</artifactId> <packaging>jar</packaging> <parent> <artifactId>book-parent</artifactId> <groupId>com.myWebApp</groupId> <version>0.0.1-SNAPSHOT</version> <relativePath>../book-parent/pom.xml</relativePath> </parent> <name>book-service</name> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>com.myWebApp</groupId> <artifactId>book-core</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> </plugin> </plugins> </build> </project>
三、book-web模块
1、book-web是web项目，在这个模块项目中他有页面以及相应的控制层组成。页面既是mvc中的视图 ，同事也包含了mvc中的控制层。
控制层代码：
package com.mr.cheng.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import com.mr.cheng.biz.UserBizDao; import com.mr.cheng.entity.User; @Controller @RequestMapping("/userController.do") public class UserController { @Autowired private UserBizDao userBizDao; @RequestMapping("/login") public String login(){ User user = new User(); user.setDescn("1111"); user.setUsername("abc"); user.setPassword("pass"); userBizDao.insert(user); return "success"; } }
spring-web配置：
<?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:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tool="http://www.springframework.org/schema/tool" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tool http://www.springframework.org/schema/tool/spring-tool-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <context:component-scan base-package="com.mr.cheng.controller" /> </beans>
spring-mvc配日志：
