2 . 定义maven路径
File - Settings - Build,Execution,Deployment_Bulid Tools_Maven
Override 其中的settings file为本地maven的 settings.xml 地址。
然后Local repository 会根据settings.xml中的仓库的地址而变化。
然后让上面的pom.xml文件生效。[Import Changes]
3 . 创建模块工程Common
File - New - Module - Maven - Parent选父工程,但是仍然将 Add as module to 置为 none - 照上面规则填好 GroupId,ArtifactId - 项目名称为 hnlp2es-common 后 一路Next
说明:将common模块放在parent同个目录下(虽然不知道为啥)
<?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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>hnlp2es-parent</artifactId>
<groupId>cn.hnlp2es.parent</groupId>
<version>1.0-SNAPSHOT</version>
<relativePath>../hnlp2es-parent/pom.xml</relativePath>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>hnlp2es-common</artifactId>
</project>
4 . 创建子模块工程 web,service,repo,entity
对着父工程右键 - New - Module - > 输入 hnlp2es-web
对着父工程右键 - New - Module - > 输入 hnlp2es-service
对着父工程右键 - New - Module - > 输入 hnlp2es-repo
对着父工程右键 - New - Module - > 输入 hnlp2es-entity
其中:
web的pom.xml
- 用jar启动,于是packaging为jar.
<?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"

<groupId>cn.hnlp2es.parent</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>cn.hnlp2es.web</groupId>
<artifactId>hnlp2es-web</artifactId>
<!-- add 打包方式 -->

</dependency>
<dependency>

<artifactId>hnlp2es-entity</artifactId>

</dependency>
<!-- add sb相关依赖 -->

</dependency>
<dependency>

<scope>test</scope>
</dependency>
</dependencies>
</project>
service 的pom.xml
<?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"

</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>cn.hnlp2es.entity</groupId>
<artifactId>hnlp2es-entity</artifactId>
<packaging>jar</packaging>
</project>
repo的pom.xml
<?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"

</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>cn.hnlp2es.repo</groupId>
<artifactId>hnlp2es-repo</artifactId>
</project>
entity的pom.xml文件
<?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"

</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>cn.hnlp2es.entity</groupId>
<artifactId>hnlp2es-entity</artifactId>
<packaging>jar</packaging>
</project>
5 .编码测试
主要在web中进行编码
java 目录下创建 com.sbaggre Package,然后在该包下新建 ApplicationStarter.java 文件;
在 com.sbaggre 下新建controller目录,然后在该目录下新建 HelloController.java 文件.
package com.sbaggre;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ApplicationStarter {
public static void main(String[] args) {
SpringApplication.run(ApplicationStarter.class, args);
}
}
package com.sbaggre.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/hello/")
public class HelloController {
@GetMapping("say")
public String sayHello(){
return "Hello World.";
}
}
6 . 启动验证
直接右键绿色三角形启动。
打开 http://localhost:8080/hello/say
显示 Hello World.
说明成功。

http://www.marsitman.com/idea/intellij-idea-create-maven-union.html
在这个过程中踩过的坑:
1-项目间依赖jar包的问题:
报错:Maven Error : Could not resolve dependencies for project
具体报错:Failed to collect dependencies for [com.xxx:jar:1.0 (compile),… -> [Help 1]
-1-确认pom.xml依赖没有写错;
-2-打开右边的Maven插件,看看有木有报错,项目里有木有灰色的(灰色的需要点亮-Unignore–参考:https://www.cnblogs.com/jimisun/p/9059728.html)
-3-关于被引用的模块项目,并不是非packaging为jar
2-springboot与spring引用的冲突
报错:Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc….
应该是版本的冲突
-1-我的解决方法是将pom.xml中的spring相关的依赖注释掉。
3-左边的 External Libraries 只有jdk,没有pom.xml中引用的包。
一般情况下,项目建好后External Libraries 就会自动添加pom中的依赖包。并且会随着pom的改变而变更。
所以可能原因是过程中maven出错了导致流程错误。
这个问题,也导致了不能在编码中利用pom中的jar包!
-1-调整pom文件中的错误,我的是web项目的packaging原为war,而应该是jar.
-2-maven 的clean - install.当子模块的install有错误的时候,将parent进行install尝试下。
4-Spring-boot启动
打开页面显示报错:Whitelabel Error Page
-知识点-通过psvm的方法,程序只能加载Application.java所在包及其子包下的内容。
而且,Application.java 文件不能直接放在main/java文件夹下,必须要建一个包把他放进去
看来得多去官网看看!
-1-(参考:https://www.cnblogs.com/JealousGirl/p/whitelabel.html)有比较全的解决方案。
-2-(参考:https://segmentfault.com/a/1190000004493460)这里有另一个报错
5-jar方式启动Spring-boot报错:springboot jar启动没有主清单属性
-1-在parent的pom中添加spring-boot-maven-plugin即可解决(参考:https://www.cnblogs.com/niceboat/p/6230448.html)
好像是这些坑吧。
