ssm+maven多模块项目整合

 

 

 

我的项目一共会分为4个模块：entity、dao、service和web

一、创建父模块

填写GroupId与ArtifactId

 

 填写项目名称和项目保存路径

 

 因为是父模块所以src包可以删除

二、创建entity子模块

右键项目选择Module

和父模块一样点击下一步

填写ArtifactId

 

点击Finish子模块创建完成

 

结构如下

 

 

 dao、service的步骤和entity子模块步骤一样，创建完成后结构如下

 

 三、创建web子模块

点击Module

勾选上选择webapp点击下一步

填写ArtifactId点击下一步

点击下一步

点击finish多模块创建完成

 

 多模块结构如下

 

可以看到idea创建时web模块的main包下的结构和其他模块不同，可以手动修改，修改完成后点击ok

正确的结构如下

 

 至此，我们的多模块创建完成，接下来整合ssm

四、添加模块之间的相关依赖

这是preant模块的pom.xml文件如下

xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

五、spring整合springMVC

 创建springmvc.xml

代码如下

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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    <context:component-scan base-package="com.chaoqi.controller"/>
    
    <mvc:annotation-driven/>
    
    <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>
beans>

 编写测试类controller

package com.chaoqi.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;


@Controller
public class TestController {
    private static final String Hello = "hello";

    @RequestMapping("/test")
    public String test() {
        return Hello;
    }

}

创建jsp页面

 

配置web-xml文件

         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:web="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

    
    
        CharacterEncodingFilter
        class>org.springframework.web.filter.CharacterEncodingFilterclass>
        
            encoding
            UTF-8
        
        
    
    
        CharacterEncodingFilter
        /*
    
    
    
        chaoqi-web
        org.springframework.web.servlet.DispatcherServlet
        
        
            contextConfigLocation
            classpath:spring/springmvc.xml
        
        1
    
    
        chaoqi-web
        /
    

接下来就是运行项目打，首先打包项目

配置完后点击OK

 

 

build完成后，结构如下

 

配置tomcat

点击运行

 

 结果如下

 

 

六、spring整合mybatis

 创建数据库    数据库采用的是mysql数据库

--学生登陆表
CREATE TABLE `user_login` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键(自增长)',
  `user_name` varchar(30) DEFAULT NULL COMMENT '用户名',
    `pass_word` varchar(30) DEFAULT NULL COMMENT '密码',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

添加两条数据

insert into user_login (user_name,pass_word) VALUES ('猪点点','12345') 
insert into user_login (user_name,pass_word) VALUES ('会飞的大象','12345') 

创建实体类

 创建UserLoginMapper 接口和xml

 

 

 

创建service接口和serviceImpl实现类

 

 创建db.properties

jdbc.driver=com.mysql.jdbc.Driver  
jdbc.host=localhost
jdbc.database=test
jdbc.userName=root
jdbc.passWord=123456
jdbc.initialSize=0  
jdbc.maxActive=20    
jdbc.maxIdle=20  
jdbc.minIdle=1  
jdbc.maxWait=1000

编写controller

package com.chaoqi.controller;

import com.chaoqi.entity.UserLogin;
import com.chaoqi.service.UserLoginService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;


@Controller
public class TestController {
    private static final String HELLO = "hello";
    @Autowired
    private UserLoginService userLoginService;

    @RequestMapping("/test")
    public String test() {
        return HELLO;
    }

    @ResponseBody
    @RequestMapping("/getUserLogin")
    public List getViideType() {
        List userLogin = userLoginService.getVideoInfo(null);
        for (UserLogin userLogins : userLogin) {

        }
        return userLogin;
    }
}
