IDEA整合SSM框架

一，环境准备

\* IDEA开发工具

\* JDK

\* Tomcat

\* Maven

二，环境配置

\* JDK和Maven配置HOME环境变量并引入Path路径，分别用java  -version和mvn -v验证

\* Maven配置工厂路径和镜像路径（从阿里云服务器下载，速度较快）

-- 路径配置 $\{MAVEN\_HOME\}\\config\\setting.xml

![70][]

<localRepository>E:/develop/apache-maven-3.5.3-bin/.m2/repository</localRepository>

-- 镜像路径

<mirrors>
        
    	 <mirror>  
    		<id>nexus-aliyun</id>  
    		<mirrorOf>central</mirrorOf>    
    		<name>Nexus aliyun</name>  
    		<url>http://maven.aliyun.com/nexus/content/groups/public</url>  
    	</mirror> 
      </mirrors>

三，搭建流程

1，创建maven项目

\* 指定JDK，注意不要选择圆框中的webapp

![70 1][]

\* 自定义名称

![70 2][]

\* 指定本地maven

\* 注意修改setting文件和maven工厂路径

![70 3][]

\* 修改maven引入方式为自动引入

![70 4][]

2，添加项目到Tomcat

\* 添加一个本地Tomcat，Tomcat Server不存在点最下面的more

![70 5][]

![70 6][]

\* 配置Tomcat名称，路径，jre路径和端口，默认浏览器

![70 7][]

\* 添加项目，Artifact不存在，install一次maven项目，添加exploded后缀，可以热部署

\* 后面名称建议和项目名称保持一致

![70 8][]

3，启动Tomcat

\* 直接点击上方启动按钮

![70 9][]

\* 启动成功，会自动弹出指定浏览器显示结果

![70 10][]

![70 11][]

\* 踩坑日记

-- 注意 ： Tomcat整合maven和maven自身路径的jdk，jre路径保持一致，不然会出现莫名错误

-- 注意 ： 报1099，8085等端口冲突，正常情况下不是端口的问题，可以先试着install

-- 注意 ： 如果自认为一切都没问题了，还不能弹出的话，可以查看下maven和Tomcat的版本问题

4，搭建SSM框架

\* pom.xml

5，Java代码

\* controller

@Controller
    @RequestMapping("/myProjectController")
    public class MyProjectController {
    
        @Autowired
        private IMyProjectService myProjectService;
    
        @RequestMapping(value = "/getAllUser", method = RequestMethod.GET)
        @ResponseBody
        public List<Map<String, Object>> getAllUser() {
            return myProjectService.getAllUser();
        }
    }

\* service -- 接口

public interface IMyProjectService {
        public List<Map<String, Object>> getAllUser();
    }

\* service -- 实现类

@Service
    public class MyProjectServiceImpl implements IMyProjectService{
    
        @Autowired
        private IMyProjectDao myProjectDao;
    
        @Override
        public List<Map<String, Object>> getAllUser() {
            return myProjectDao.getAllUser();
        }
    }

\* dao -- 接口

@Repository
    public interface IMyProjectDao {
        public List<Map<String, Object>> getAllUser();
    }

\* dao -- mapper

<?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.gupao.test.dao.IMyProjectDao">
    
        <select id="getAllUser" resultType="map">
            SELECT *
            FROM
              USER_T
        </select>
    </mapper>

6，踩坑日记

\* No mapping found for HTTP request with URI \[\*\*\*\*\*\*\*\*\*\] in DispatcherServlet with name 'dispatch

spring-mvc.xml配置 :

<mvc:annotation-driven/>

\* 自动扫描包路径 :

<context:component-scan base-package="com.gupao.*.controller" />

\* class path resource \[spring/\] cannot be resolved to URL because it does not exist 这个报错比较坑了

完全找不到原因，在target目录中，也确实找不到resource下自定义目录的文件

![70 14][]

解决：在pom.xml中添加配置

<resources>
          <resource>
            <directory>src/main/java</directory>
            <includes>
              <include>**/*.properties</include>
              <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
          </resource>
        </resources>

\* 最后，因为没有做页面，想通过GET方式直接返回查询结果到页面，走通一套流程。结果一直报404，但是看

控制台确实SQL已经打印出来了，这是因为controller中没有添加@ResponseBody转换为json转回，页面不

响应List<Map>，但是报404确实有点误导了
