Meavn多Module搭建Springmvc + MyBatis + Druid 以及项目热部署

1493212884

IDE：idea + meavn

框架：Spring + Springmvc + MyBatis + Druid

如何new project new module 就此省略

演示项目暂时new 了这几个module，分别的packaging打包类型为

apeweb-bean(jar)

apeweb-core(jar)

apeweb-mybatis(jar)

apeweb-service(jar)

apeweb-web(war)

apeweb(pom)

其中，父模块必须以pom打包类型

然后是添加Spring mybatis druid相关依赖 <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency>

好吧，其实跟普通的ssm搭建没什么区别，但是需要注意的是添加module依赖问题

还有就是到 File -> Project Structure -> Project Settings -> Facets 添加一下Web路径

搭建遇到的小问题
Java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for PersonMapper.listAll
报错原因：没有成功引入mybatis 模块的依赖，导致找不到PersonMapper报异常

当时的pom.xml已经添加了apeweb-mybatis依赖

<dependency>
     <groupId>com.ape</groupId>
     <artifactId>apeweb-mybatis</artifactId>
     <version>1.0-SNAPSHOT</version>
 </dependency>

解决办法： File -> Project Structure -> Project Settings -> Artifacts 添加配置
idea简单的两步实现热部署
何为热部署，就是修改java代码 jsp页面自动编译，无需重新部署项目

上图，修改 Upldate 跟 frame deactivation 为 Update classes and resources

然后以Debug模式运行项目，一定要Debug模式！！！
