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

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

 

二、建立实体类和相应的mapper以及xml

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

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"?>

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