#### 2 Gradle与IDEA整合 ####

##### 2.10 使用Gradle搭建SSM项目 #####

###### 2.10.1 在IDEA中创建web工程 ######

在 idea 新版本的创建项目中,无法自己选择创建项目是普通 java 工程还是 web 工程了【IDEA 旧版本是可以的】，

所以我 们如果想创建 web 工程，只需要自己在 src/main/目录下添加 `webapp/WEB-INF/web.xml`及页面即可。

举个栗子：

新建项目

这次我们就直接在`高级设置` 中选择使用本地的gradle，而不是IDEA 插件指定的版本，直接创建

![在这里插入图片描述][30e799f321504b16913d1c1a417973f4.png_pic_center]

这次我们创建的工程，它使用就会是我们本地的gradle 了

> 老师的IDEA 那个版本还不行

如果是要做一个war 工程，先来一个war 插件

记得刷一下

接下来在我们对 gradle 的其它知识点讲解之前我们先提一下在 gradle 文件中需要用到的groovy 语法。

如果想把这个web 工程这个东西运行起来，分为以下几步：

① 导入添加对应的依赖信息

plugins {
        
        id 'java'
        id 'war'
    }
    
    group = 'com.dingjiaxiong'
    version = '1.0-SNAPSHOT'
    
    repositories {
        
        mavenCentral()
    }
    
    dependencies {
        
        implementation 'org.springframework:spring-beans:4.1.7.RELEASE'
        implementation 'org.springframework:spring-web:4.1.7.RELEASE'
        implementation 'org.springframework:spring-webmvc:4.1.7.RELEASE'
        implementation 'org.springframework:spring-tx:4.1.7.RELEASE'
        implementation 'org.springframework:spring-test:4.0.5.RELEASE'
        implementation 'org.springframework:spring-jdbc:4.1.7.RELEASE'
    
        implementation 'org.mybatis:mybatis-spring:1.2.3'
        implementation 'org.mybatis:mybatis:3.3.0'
    
        implementation 'mysql:mysql-connector-java:5.1.36'
        implementation 'com.alibaba:druid:1.0.15'
    
        implementation "com.fasterxml.jackson.core:jackson-databind:2.2.3"
        implementation "com.fasterxml.jackson.core:jackson-annotations:2.2.3"
        implementation "com.fasterxml.jackson.core:jackson-core:2.2.3"
    
        implementation 'org.aspectj:aspectjweaver:1.8.6'
        implementation 'log4j:log4j:1.2.17'
        implementation 'org.slf4j:slf4j-api:1.7.25'
        implementation 'jstl:jstl:1.2'
        compileOnly 'javax.servlet:servlet-api:2.5'
        testImplementation group: 'junit', name: 'junit', version: '4.12'
    }

记得刷一下

在src 下的main 目录下添加一个webapp 目录

![在这里插入图片描述][0292455c8e7e4d70b0c691f450d6d27c.png_pic_center]

注意和普通的文件夹不一样，有个蓝点【这说明war 插件是生效的】

接着就是创建`web.xml` 文件了

② 编写对应的配置文件

web.xml

扫描包路径创建出来

连接的是本机上的test 数据库

准备一张`admin` 数据表

    CREATE TABLE `admin`  (

    <configuration>
    
    
    
    
    </configuration>

③ 编写业务逻辑代码

![在这里插入图片描述][e2e4ada87caf4cb8b5bff95e493f6c49.png_pic_center]

一共就是这些层

Admin.java

package com.dingjiaxiong.bean;
    
    public class Admin {
        
        private Integer id;
        private String username;
        private String email;
    
        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 getEmail() {
        
            return email;
        }
    
        public void setEmail(String email) {
        
            this.email = email;
        }
    
        @Override
        public String toString() {
        
            return "Admin{" +
                    "id=" + id +
                    ", username='" + username + '\'' +
                    ", email='" + email + '\'' +
                    '}';
        }
    }

AdminController.java

package com.dingjiaxiong.controller;
    
    import com.dingjiaxiong.bean.Admin;
    import com.dingjiaxiong.service.AdminService;
    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
    @RequestMapping("/admin")
    public class AdminController {
        
    
        @Autowired
        private AdminService adminService;
    
        @RequestMapping("/list")
        @ResponseBody
        public List<Admin> getAdminList() {
        
            System.out.println("dada");
            return adminService.getAdminList();
        }
    
    }

AdminMapper.java

package com.dingjiaxiong.dao;
    
    import com.dingjiaxiong.bean.Admin;
    
    import java.util.List;
    
    public interface AdminMapper {
        
        List<Admin> getAdminList();
    }

AdminService.java

package com.dingjiaxiong.service;
    
    import com.dingjiaxiong.bean.Admin;
    import com.dingjiaxiong.dao.AdminMapper;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import org.springframework.transaction.annotation.Transactional;
    
    import java.util.List;
    
    @Service
    public class AdminService {
        
    
        @Autowired
        private AdminMapper adminMapper;
    
        @Transactional
        public List<Admin> getAdminList() {
        
            return adminMapper.getAdminList();
        }
    }

还有个SQL mapper 映射文件

AdminMapper.xml

<?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.dingjiaxiong.dao.AdminMapper">
    
        <select id="getAdminList" resultType="com.dingjiaxiong.bean.Admin">
            select id, username, email
            from admin
        </select>
    
    
    </mapper>

其实就是把数据库里面的两条用户信息查出来

【到这里其实整个项目就算创建完成了】

④ 第四步，进行部署，我们接着看下去
