ssm 整合（方案二 maven）

通过maven来整合ssm方便很多，至少不用去找jar包

具体架构如下：

1、配置pom.xml

<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">

  <build>

2、

配置jdbc.properties

#JDBCdriver
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver

#JDBC
jdbc.url=你的连接服务器
jdbc.username=数据库账号
jdbc.password=数据库密码
jdbc.publickey=阿里秘钥

jdbc.dbcp.initialSize=10
jdbc.dbcp.maxActive=500
jdbc.dbcp.maxIdle=10
jdbc.dbcp.minIdle=1
jdbc.dbcp.maxWait=120000

3、

log4j.properties

log4j.rootLogger=DEBUG,Console,File  

log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n  

log4j.logger.com.mybatis=DEBUG
log4j.logger.com.mybatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.mybatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.mybatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG  

4、

spring-source.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:property-placeholder location="classpath:jdbc.properties" />
    <!-- 自动扫描(自动注入)，扫描me.gacl.service这个包以及它的子包的所有使用@Service注解标注的类 -->
    <context:component-scan base-package="com.tp.soft" />
</beans>

5、

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>

</beans>

6、

myBatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   <!-- 配置映射类的别名 -->
    <typeAliases>
     <!-- 配置entity下的所有别名 别名首字母小写 -->
     <package name="com.tp.soft.entity"/>
   </typeAliases>  

</configuration>  

7、

UserMapper.java

package com.tp.soft.dao;

import com.tp.soft.entity.User;

public interface UserMapper {
    public User getUserById(int id);
}

8、

UserMapper.xml

<?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.tp.soft.dao.UserMapper" >
   <select id="getUserById" parameterType="int" resultType="user">
        select * from AU_USER where userid = #{id}
   </select>

</mapper>

9、

User.java

package com.tp.soft.entity;

import java.io.Serializable;

public class User implements Serializable{

    /**
     *
     */
    private static final long serialVersionUID = -1695973853274402680L;

    private int userid;

    private String login_name;

    private String login_pwd;

    public User() {

    }

    public User(int userid, String login_name, String login_pwd) {
        super();
        this.userid = userid;
        this.login_name = login_name;
        this.login_pwd = login_pwd;
    }

    public int getUserid() {
        return userid;
    }

    public void setUserid(int userid) {
        this.userid = userid;
    }

    public String getLogin_name() {
        return login_name;
    }

    public void setLogin_name(String login_name) {
        this.login_name = login_name;
    }

    public String getLogin_pwd() {
        return login_pwd;
    }

    public void setLogin_pwd(String login_pwd) {
        this.login_pwd = login_pwd;
    }

}

9、

UserSvc.java

package com.tp.soft.service;

import com.tp.soft.entity.User;

public interface UserSvc {
    public User getUser(int id);
}

UserSvcImpl.java

package com.tp.soft.service.impl;

import javax.annotation.Resource;

import org.springframework.dao.DataAccessException;
import org.springframework.stereotype.Service;

import com.tp.soft.dao.UserMapper;
import com.tp.soft.entity.User;
import com.tp.soft.service.UserSvc;

@Service("userService")
public class UserSvcImpl implements UserSvc{

    @Resource
    private UserMapper userMapper;

    public User getUser(int id) {
        User user = null;
        try{
            user = userMapper.getUserById(id);
        }catch (DataAccessException e) {
            System.out.println(e.getLocalizedMessage());
        }
        return user;
    }

}

10、测试junit

package juint;

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 com.tp.soft.service.UserSvc;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/spring-source.xml",
        "classpath:spring/spring-mybatis.xml" })
public class TestCase {

    @Autowired
    private UserSvc userSvc;

    @Test
    public void testAddUser() {
        userSvc.getUser(21);
    }
}

结果：

到此spring+mybatis配置完成，接下来配置springmvc

spring-mvc.xml
