IntelliJ IDEA整合SSM框架

SSM框架整合(IntelliJ IDEA + maven + Spring + SpringMVC + MyBatis)

1. 创建maven项目

1.1 File–>New Module,进入创建项目窗口

1.2 点击Next，填写GroupId、ArtifactId和Version

1.3 在Properties中添加一个参数 archetypeCatalog=internal，不加这个参数，在maven生成骨架的时候将会非常慢，有时候直接卡住。

1.4 填写Module name

1.5 生成maven的项目骨架之后，我们还需要手动在 src/main 下创建 java目录。完整的项目结构如下图

1.6 这里的目录建好之后还需要设置一下，让idea识别目录作用，选择File-Project Structure

到此为止，项目的框架基本搭建完成

2. 项目配置文件

2.1 这里使用maven来引入项目所需要的jar包，所以也就不需要手动来管理jar包了

pom.xml

2.2 这里可以控制输出格式和内容，有兴趣的可以自己设置

logback.xml

    
        
            %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
        
    
    
        
    

2.3 新建jdbc.properties文件

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
#数据库地址
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8&useSSL=false
#用户名
jdbc.username=root
#密码
jdbc.password=201314
#最大连接数
c3p0.maxPoolSize=30
#最小连接数
c3p0.minPoolSize=10
#关闭连接后不自动commit
c3p0.autoCommitOnClose=false
#获取连接超时时间
c3p0.checkoutTimeout=10000
#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2

2.4 新建log4j配置文件

log4j.properties

log4j.rootLogger=INFO,Console,File  

#控制台日志  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH:mm:ss}][%C] - %m%n  

#普通文件日志  
log4j.appender.File=org.apache.log4j.RollingFileAppender  
log4j.appender.File.File=logs/ssm.log  
log4j.appender.File.MaxFileSize=10MB  
#输出日志，如果换成DEBUG表示输出DEBUG以上级别日志  
log4j.appender.File.Threshold=ALL  
log4j.appender.File.layout=org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH:mm:ss}][%C] - %m%n

2.5 新建spring和mybatis整合所需的配置文件

spring-mybatis.xml

2.6 新建springmvc配置文件

spring-mvc.xml

2.7 新建web.xml配置文件

web.xml

3.0 测试

3.1 创建数据库表

3.2 配置类

User

package com.ssm.model;

public class User {

private Integer id;
private String username;
private String password;


public Integer getId() {
    return id;
}

public void setId(Integer id) {
    this.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) {
    this.password = password;
}

@Override
public String toString() {
    return "User{" +
            "id=" + id +
            ", username='" + username + '\'' +
            ", password='" + password + '\'' +
            '}';
}
}

IUserDao

package com.ssm.dao;

import com.ssm.model.User;
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;

public class IUserDaoTest {

    @Autowired
    private IUserDao dao;

    @Test
    public void testSelectUser(){
        Integer id = 1;
        User user = dao.selectUser(id);
        System.out.println(user);

    }
}

UserDao.xml

    SELECT * FROM user WHERE id = #{id}
