7: Spring+SpringMVC+Maven+Mybatis+MySQL项目搭建

开发环境介绍

IDE: MyEclipse 10.7
jdk: 1.6
maven：apache-maven-3.2.5
基本环境只要上面这些就行.
Maven的安装

1、创建表，并插入数据：

----------------------------------------------创建表
CREATE TABLE `t_user` (
  `USER_ID` int(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` char(30) NOT NULL,
  `USER_PASSWORD` char(10) NOT NULL,
  PRIMARY KEY (`USER_ID`),
  KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

---------------------------------------插入数据
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');

2、Maven工程创建,选择快速框架

5 、添加包的依赖，编辑pom.xml文件添加如下依赖：

  4.0.0
  com.gp6
  MyMavenProject
  0.0.1-SNAPSHOT
  war
  
  
        
        3.2.8.RELEASE
        
        1.6.6
        1.2.12
        
        4.10
        
        3.2.1
  

  
        
        
            org.springframework
            spring-core
            ${spring.version}
        
        
            org.springframework
            spring-webmvc
            ${spring.version}
        
        
            org.springframework
            spring-context
            ${spring.version}
        
        
            org.springframework
            spring-context-support
            ${spring.version}
        
        
            org.springframework
            spring-aop
            ${spring.version}
        
        
            org.springframework
            spring-aspects
            ${spring.version}
        
        
            org.springframework
            spring-tx
            ${spring.version}
        
        
            org.springframework
            spring-jdbc
            ${spring.version}
        
        
            org.springframework
            spring-web
            ${spring.version}
        

        
        
            junit
            junit
            ${junit.version}
            test
        

        
        
        
            log4j
            log4j
            ${log4j.version}
        
        
            org.slf4j
            slf4j-api
            ${slf4j.version}
        
        
            org.slf4j
            slf4j-log4j12
            ${slf4j.version}
        
        

        
        
            org.springframework
            spring-test
            ${spring.version}
            test
        

        
        
            org.mybatis
            mybatis
            ${mybatis.version}
        

        
        
            org.mybatis
            mybatis-spring
            1.2.0
        

        
        
            mysql
            mysql-connector-java
            5.1.29
        
    

6、配置文件：

6、1 创建 mybatis包下添加mybatis-config.xml文件（mybatis配置文件）：

Paste_Image.png

6. 2、 创建 properties包下添加jdbc.properties文件（数据源配置文件）：

Paste_Image.png

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/study
jdbc_username=root
jdbc_password=123456

6. 3、 创建 mapper包下userMapper.xml配置文件（表映射文件）：

Paste_Image.png

一定要注意这一行的值是否正确

  





    
        
        
        
    
    
    
    
    
        SELECT * FROM t_user WHERE USER_ID = #{userId}
    

6. 4、 创建 spring配置文件application.xml：

Paste_Image.png

       
     
        
            
               classpath:properties/*.properties
                
            
        
    

    
    
        
        
            
            
       
        
            ${jdbc_driverClassName}
        
        
            ${jdbc_url}
        
        
            ${jdbc_username}
        
        
            ${jdbc_password}
        
    

    
    
        
    

    
    
        
        
        
        
    

    
    

7 接口和类的配置：

Paste_Image.png

7.1 、com.gp6.entity 下添加User.Java文件：

package com.gp6.entity;

public class User {
    private Integer userId;  
    private String userName;  
    private String userPassword;
    
    public Integer getUserId() {
        return userId;
    }
    public void setUserId(Integer userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getUserPassword() {
        return userPassword;
    }
    public void setUserPassword(String userPassword) {
        this.userPassword = userPassword;
    }  
}

7.2、com.gp6.mapper下添加Usermapper.java文件：

package com.gp6.mapper;

import com.gp6.entity.User;

public interface UserMapper {
    
    /**
     * @param userId
     * @return User
     */
    public User selectUserById(Integer userId);  
}

7.3、com.gp6.service下添加UserService.java接口和UserServiceImpl实现类：

• UserService.java

package com.gp6.service;

import com.gp6.entity.User;

public interface UserService {
    public User selectUserById(Integer userId); 
}

• UserServiceImpl.java

package com.gp6.service.impl;

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

import com.gp6.entity.User;
import com.gp6.mapper.UserMapper;
import com.gp6.service.UserService;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;
    
    @Override
    public User selectUserById(Integer userId) {
         return userMapper.selectUserById(userId);  
    }

}

8 单元测试

Paste_Image.png

8.1 BaseTest

package com.gp6.baseTest;

import org.junit.runner.RunWith;  
import org.springframework.test.context.ContextConfiguration;  
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;  
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  

//指定bean注入的配置文件  
@ContextConfiguration(locations = { "classpath:application.xml" })  
//使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner  
@RunWith(SpringJUnit4ClassRunner.class) 
public class BaseTest extends AbstractJUnit4SpringContextTests{

}

8.2 UserServiceTest

package com.gp6.serviceTest;

import org.springframework.beans.factory.annotation.Autowired;
import org.junit.Test;  
import com.gp6.baseTest.BaseTest;  
import com.gp6.entity.User;
import com.gp6.service.UserService;

public class UserServiceTest extends BaseTest {
    @Autowired  
    private UserService userService; 

    @Test  
    public void selectUserByIdTest(){  
        User user = userService.selectUserById(1);  
        System.out.println(user.getUserName() + ":" + user.getUserPassword());
    }  
}

8.3 运行单元测试，UserServiceTest右键Run As –>Junit Test，运行结果：

8.4 添加日志配置

Paste_Image.png

• log4j.properties

log4j.rootLogger=DEBUG,Console,Stdout  
  
#Console  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  
  
log4j.logger.java.sql.ResultSet=INFO  
log4j.logger.org.apache=INFO  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG   
  
log4j.appender.Stdout = org.apache.log4j.DailyRollingFileAppender    
log4j.appender.Stdout.File = E://WorkSpace/Study/logs/MyMavenProject/log.log   
log4j.appender.Stdout.Append = true    
log4j.appender.Stdout.Threshold = DEBUG     
log4j.appender.Stdout.layout = org.apache.log4j.PatternLayout    
log4j.appender.Stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n    

到这里配置好spring+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

这里开始添加spirngMVC，并转换maven工程为web项目

9 、转换成web项目：

• Eclipse

  
  
  

  Paste_Image.png

• MyEclipse

Paste_Image.png

将红框里面的勾去掉，确定（OK）,然后重新打开刚刚那个页面，把Dynamic web Module勾上，就会看到红框的内容，点击：

至此,项目已转为ＷＥＢ项目！

10 配置springmvc

10.1、pom.xml文件添加依赖，修改后配置如下：

  4.0.0
  com.gp6
  MyMavenProject
  0.0.1-SNAPSHOT
  war
  
  
        
        3.2.8.RELEASE
        
        1.6.6
        1.2.12
        
        4.11
        
        3.2.1
  

  
        
            junit
            junit
            ${junit.version}
            test
        

        
        
        
            log4j
            log4j
            ${log4j.version}
        
        
            org.slf4j
            slf4j-api
            ${slf4j.version}
        
        
            org.slf4j
            slf4j-log4j12
            ${slf4j.version}
        
        

        
        
            org.springframework
            spring-test
            ${spring.version}
            test
        
        
            mysql
            mysql-connector-java
            5.1.29
        
        
          
          
            javax  
            javaee-api  
            6.0  
            provided  
          

          
          
            javax  
            javaee-web-api  
            6.0  
            provided  
          
        
    
  

其实也就增加了下面两个

  
          
            javax  
            javaee-api  
            6.0  
            provided  
          

          
          
            javax  
            javaee-web-api  
            6.0  
            provided  
         

10.2、在src/main/resource中添加springmvc文件夹，然后添加文件spring-mvc.xml，内容如下：

10.3、配置web.xml

        dispatcherServlet
  
        /*
    

    
    Archetype Created Web Application
    
    
    
        index.jsp
    

    
    
        contextConfigLocation
        classpath:application.xml
    
    
    
    
        webAppRootKey
        springmvc.root
    

    
    
        SpringEncodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
        
            forceEncoding
            true
        
    
    
        SpringEncodingFilter
        /*
    
    
    
    
        org.springframework.web.context.ContextLoaderListener
    

    
    
        dispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            
            classpath:springmvc/spring-mvc.xml
        
        1
    
    
    
    
        dispatcherServlet
        /*
    

    
    
        
        404
        /WEB-INF/errorpage/404.jsp
    
    
        
        405
        /WEB-INF/errorpage/405.jsp
    
    
        
        500
        /WEB-INF/errorpage/500.jsp
    

10.4、添加index.jsp，在src/main/webapp/WEB-INF下新建一个文件夹jsp,添加一个index.jsp，内容如下：

Paste_Image.png

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>


Hello World!
用户名： ${user.userName}

 密码：${user.userPassword}

10.5、写controller

Paste_Image.png

在src/main/java下新建一个包com.gp6.controller.然后新建一个类UserController.java,其内容如下

package com.gp6.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.gp6.entity.User;
import com.gp6.service.UserService;

@Controller
public class UserController {
    @Resource  
    private UserService userService;  

    @RequestMapping("/")    
    public ModelAndView getIndex(){      
        ModelAndView modelAndView = new ModelAndView("index");   
        User user = userService.selectUserById(1);  
        modelAndView.addObject("user", user);   
        return modelAndView;    
    }    
}

10.6 运行！！！！完成！
