SSM框架之整合(Maven实例)

有不少朋友在maven中因为pom文件依赖的事导致报错

今天我这个快速搭建ssm框架，确保在jdk7或者jdk8的环境，tomcat没什么要求。但如果要用jdk8的话，最好用run as中的server启动tomcat否则如果用maven build启动，输入浏览器地址进入jsp页面会报无法编译Jsp错误，这是因为maven自带tomcat6.jdk版本与tomcat存在冲突。导致jsp编译的环境有问题。

一、导入正确依赖

<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">

	<build>

		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>

				<version>2.0.2</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
				</configuration>
			</plugin>

		</plugins>
	</build>
</project>

二、建立实体类和相应的mapper以及xml

package cn.entity;

public class User {

	
	private Integer Id;
	private String userName;
	private String PassWord;
	public Integer getId() {
		return Id;
	}
	public void setId(Integer id) {
		Id = id;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassWord() {
		return PassWord;
	}
	public void setPassWord(String passWord) {
		PassWord = passWord;
	}
	
	
}

package cn.mapper;

import cn.entity.User;

public interface UserMapper {

    
    public User selectUserInfo(String userName);
}

<?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="cn.mapper.UserMapper">

<select id="selectUserInfo" parameterType="String" resultType="User">
select * from `user` where userName=#{userName}

</select>

</mapper>

三、建立service以及service的实现类

package cn.service;

import cn.entity.User;

public interface UserService {

    
    public User selectUserInfo(String userName);
}

package cn.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.entity.User;
import cn.mapper.UserMapper;
import cn.service.UserService;

@Service
public class UserServiceImpl implements UserService {
    
    @Autowired
    private UserMapper userMapper;
    
    @Override
    public User selectUserInfo(String userName) {
        // TODO Auto-generated method stub
        return userMapper.selectUserInfo(userName);
    }

}

四、进行Junit测试，确保application-config.xml的配置和Mybatis配置正确

package cn.test;

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 cn.entity.User;
import cn.mapper.UserMapper;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:application-config.xml")
public class JunitTest {

    
    @Autowired
    private UserMapper userMapper;
    
    @Test
    public void testName() throws Exception {
        
        User user = userMapper.selectUserInfo("youcong");
        System.out.println(user.getPassWord());
        
    }
}

五、ssm的基本配置xml文件

application-config.xml配置文件

<?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"

        http://www.springmodules.org/schema/ehcache http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd">

    <!-- 自动扫描(自动注入) -->
    <context:component-scan base-package="cn.service" />

    </bean>


    <!-- myBatis文件 -->
    <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="configLocation" value="classpath:mybatis-config.xml" />
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.mapper" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
    <!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    </bean>

    <!-- 配置事物的注解方式注入 -->
    <tx:annotation-driven transaction-manager="transactionManager" />


</beans>
