開發(fā)環(huán)境介紹
IDE: MyEclipse 10.7
jdk: 1.6
maven:apache-maven-3.2.5
基本環(huán)境只要上面這些就行.
Maven的安裝
1、創(chuàng)建表源请,并插入數(shù)據(jù):
----------------------------------------------創(chuàng)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
---------------------------------------插入數(shù)據(jù)
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工程創(chuàng)建,選擇快速框架
3 輸出項(xiàng)目名卸耘,包(Packaging,如果只是普通的項(xiàng)目刊侯,選jar就好了声离,如果是web項(xiàng)目就選war芒炼,這里是web項(xiàng)目,所以選擇war)
4术徊、創(chuàng)建好的目錄如下:
5 本刽、添加包的依賴,編輯pom.xml文件添加如下依賴:
<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">

6、配置文件:
6子寓、1 創(chuàng)建 mybatis包下添加mybatis-config.xml文件(mybatis配置文件):
<?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>
</configuration>
6. 2暗挑、 創(chuàng)建 properties包下添加jdbc.properties文件(數(shù)據(jù)源配置文件):
jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/study
jdbc_username=root
jdbc_password=123456
6. 3、 創(chuàng)建 mapper包下userMapper.xml配置文件(表映射文件):
一定要注意<mapper namespace="com.gp6.mapper.UserMapper">這一行的值是否正確
<?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.gp6.mapper.UserMapper">
<!--設(shè)置domain類和數(shù)據(jù)庫(kù)中表的字段一一對(duì)應(yīng)斜友,注意數(shù)據(jù)庫(kù)字段和Entity類中的字段名稱不致炸裆,此處一定要!-->
<resultMap id="BaseResultMap" type="com.gp6.entity.User">
<id column="USER_ID" property="userId" jdbcType="INTEGER" />
<result column="USER_NAME" property="userName" jdbcType="CHAR" />
<result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />
</resultMap>
<!-- 查詢單條記錄 -->
<select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
SELECT * FROM t_user WHERE USER_ID = #{userId}
</select>
</mapper>
6. 4鲜屏、 創(chuàng)建 spring配置文件application.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" xmlns:context="http://www.springframework.org/schema/context"

<!-- 自動(dòng)掃描了所有的XxxxMapper.xml對(duì)應(yīng)的mapper接口文件,這樣就不用一個(gè)一個(gè)手動(dòng)配置Mpper的映射了洛史,只要Mapper接口類和Mapper映射文件對(duì)應(yīng)起來就可以了惯殊。 -->

此時(shí)spring是通過識(shí)別mapper.xml中的 <mapper namespace="com.XXX.XXX"> namespace的值來確定對(duì)應(yīng)的Mapper.class的。 -->
<!-- <property name="mapperLocations" value="classpath:mapper/*.xml"/> -->
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
</bean>
<!-- 自動(dòng)掃描注解的bean -->
<context:component-scan base-package="com.gp6.service" />
</beans>
7 接口和類的配置:
7.1 捆毫、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址愿、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實(shí)現(xiàn)類:
- 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 單元測(cè)試
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" })
//使用標(biāo)準(zhǔn)的JUnit @RunWith注釋來告訴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 運(yùn)行單元測(cè)試冻璃,UserServiceTest右鍵Run As –>Junit Test,運(yùn)行結(jié)果:
8.4 添加日志配置
- 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
到這里配置好spring+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
這里開始添加spirngMVC损合,并轉(zhuǎn)換maven工程為web項(xiàng)目
9 省艳、轉(zhuǎn)換成web項(xiàng)目:
-
Eclipse
MyEclipse
將紅框里面的勾去掉,確定(OK),然后重新打開剛剛那個(gè)頁(yè)面嫁审,把Dynamic web Module勾上跋炕,就會(huì)看到紅框的內(nèi)容,點(diǎn)擊:
配置如下,然后點(diǎn)擊OK
至此,項(xiàng)目已轉(zhuǎn)為WEB項(xiàng)目律适!
10 配置springmvc
10.1辐烂、pom.xml文件添加依賴,修改后配置如下:
<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">

10.2捂贿、在src/main/resource中添加springmvc文件夾纠修,然后添加文件spring-mvc.xml,內(nèi)容如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>
</beans>
10.3厂僧、配置web.xml
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<!-- /*時(shí),匹配不到j(luò)sp頁(yè)面 -->
<url-pattern>/*</url-pattern>
</servlet-mapping>

</error-page>
</web-app>
10.4、添加index.jsp,在src/main/webapp/WEB-INF下新建一個(gè)文件夾jsp,添加一個(gè)index.jsp辰妙,內(nèi)容如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
用戶名: ${user.userName}<br>
密碼:${user.userPassword}<br>
</body>
</html>
10.5鹰祸、寫controller
在src/main/java下新建一個(gè)包c(diǎn)om.gp6.controller.然后新建一個(gè)類UserController.java,其內(nèi)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;
}
}
