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

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，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 輸出項目名，包（Packaging，如果只是普通的項目，選jar就好了，如果是web項目就選war，這里是web項目，所以選擇war）

4、創(chuàng)建好的目錄如下：

5 、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">

        </dependency>
    </dependencies>

</project>

6、配置文件：

6、1 創(chuàng)建 mybatis包下添加mybatis-config.xml文件（mybatis配置文件）：
Paste_Image.png
<?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、 創(chuàng)建 properties包下添加jdbc.properties文件（數(shù)據(jù)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、 創(chuàng)建 mapper包下userMapper.xml配置文件（表映射文件）：
Paste_Image.png
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)庫中表的字段一一對應(yīng)，注意數(shù)據(jù)庫字段和Entity類中的字段名稱不致，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、 創(chuàng)建 spring配置文件application.xml：
Paste_Image.png
<?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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    
    xsi:schemaLocation=
           "http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/context  
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

     <!-- 引入jdbc配置文件 -->  
     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
               <value>classpath:properties/*.properties</value>
                <!--要是有多個配置文件，只需在這里繼續(xù)添加即可 -->
            </list>
        </property>
    </bean>

    <!-- 配置數(shù)據(jù)源 -->
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!-- 不使用properties來配置 -->
        <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
            <property name="url" value="jdbc:mysql://localhost:3306/study" /> 
            <property name="username" value="root" /> 
            <property name="password" value="123456" /> -->
            
            
       <!-- 使用properties來配置 ,建議使用-->
        <property name="driverClassName">
            <value>${jdbc_driverClassName}</value>
        </property>
        <property name="url">
            <value>${jdbc_url}</value>
        </property>
        <property name="username">
            <value>${jdbc_username}</value>
        </property>
        <property name="password">
            <value>${jdbc_password}</value>
        </property>
    </bean>

    <!-- 自動掃描了所有的XxxxMapper.xml對應(yīng)的mapper接口文件，這樣就不用一個一個手動配置Mpper的映射了，只要Mapper接口類和Mapper映射文件對應(yīng)起來就可以了。 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.gp6.dao" />
    </bean>

    <!-- 配置Mybatis的文件 ，mapperLocations配置**Mapper.xml文件位置，configLocation配置mybatis-config文件位置-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 如果Mapper.xml與Mapper.class在同一個包下且同名，spring掃描Mapper.class的同時會自動掃描同名的Mapper.xml并裝配到Mapper.class。
        如果Mapper.xml與Mapper.class不在同一個包下或者不同名，就必須使用配置mapperLocations指定mapper.xml的位置。
        此時spring是通過識別mapper.xml中的 <mapper namespace="com.XXX.XXX"> namespace的值來確定對應(yīng)的Mapper.class的。 -->
        <!-- <property name="mapperLocations" value="classpath:mapper/*.xml"/>   -->
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
    </bean>

    <!-- 自動掃描注解的bean -->
    <context:component-scan base-package="com.gp6.service" />

</beans>

7 接口和類的配置：

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實現(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 單元測試

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 運行單元測試，UserServiceTest右鍵Run As –>Junit Test，運行結(jié)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

到這里配置好spring+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

這里開始添加spirngMVC，并轉(zhuǎn)換maven工程為web項目

9 、轉(zhuǎn)換成web項目：

  • Eclipse


    Paste_Image.png

  • MyEclipse

Paste_Image.png

將紅框里面的勾去掉，確定（OK）,然后重新打開剛剛那個頁面，把Dynamic web Module勾上，就會看到紅框的內(nèi)容，點擊：

Paste_Image.png

配置如下,然后點擊OK

Paste_Image.png

至此,項目已轉(zhuǎn)為ＷＥＢ項目！

10 配置springmvc

10.1、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">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.gp6</groupId>
  <artifactId>MyMavenProject</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  
  <properties>
        <!-- spring版本號 -->
        <spring.version>3.2.8.RELEASE</spring.version>
        <!-- log4j日志文件管理包版本 -->
        <slf4j.version>1.6.6</slf4j.version>
        <log4j.version>1.2.12</log4j.version>
        <!-- junit版本號 -->
        <junit.version>4.11</junit.version>
        <!-- mybatis版本號 -->
        <mybatis.version>3.2.1</mybatis.version>
  </properties>

  <dependencies>
        <!-- 添加Spring依賴 -->
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>

        <!-- 日志文件管理包 -->
        <!-- log start -->
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>${log4j.version}</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <!-- log end -->

        <!--spring單元測試依賴 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
            <scope>test</scope>
        <!-- mysql驅(qū)動包 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.29</version>
        </dependency>
        
        <!-- javaee-api包 注意和項目使用的JDK版本對應(yīng) -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  

        <!-- javaee-web-api包 注意和項目使用的JDK版本對應(yīng) -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-web-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  
        
    </dependencies>
  
</project>

其實也就增加了下面兩個

<!-- javaee-api包 注意和項目使用的JDK版本對應(yīng) -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  

        <!-- javaee-web-api包 注意和項目使用的JDK版本對應(yīng) -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-web-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>
10.2、在src/main/resource中添加springmvc文件夾，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"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:mvc="http://www.springframework.org/schema/mvc"
  xsi:schemaLocation="

    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context
