EDAS 中的 Spring Boot 开发

本文主要针对使用 Spring Boot 开发应用的用户，介绍如何快速让 HSF 在 Spring Boot 中运行，并提供了完整的 Demo下载。

开发在 EDAS 中运行的 Spring Boot 项目


开发 Spring Boot 项目需要使用 Servlet 3.0 及以上版本，同时保持生成环境和 Spring Boot 编译环境 JDK 版本一致。具体开发步骤参见下文。

1. 
   创建 Web 项目，引入 Spring Boot 依赖包。
   pom.xml[backcolor=transparent] [backcolor=transparent]<!-- 打包方式由JAR 改为 WAR -->
2. [backcolor=transparent] [backcolor=transparent]<packaging>[backcolor=transparent]war[backcolor=transparent]</packaging>
4. [backcolor=transparent] [backcolor=transparent]<!-- 添加 spring-boot-starter-parent 依赖 -->
5. [backcolor=transparent] [backcolor=transparent]<parent>
6. [backcolor=transparent]     [backcolor=transparent]<groupId>[backcolor=transparent]org.springframework.boot[backcolor=transparent]</groupId>
7. [backcolor=transparent]     [backcolor=transparent]<artifactId>[backcolor=transparent]spring-boot-starter-parent[backcolor=transparent]</artifactId>
8. [backcolor=transparent]     [backcolor=transparent]<version>[backcolor=transparent]1.4.1.RELEASE[backcolor=transparent]</version>
9. [backcolor=transparent] [backcolor=transparent]</parent>
11. [backcolor=transparent] [backcolor=transparent]<!-- Spring Boot 依赖，这里必须排除嵌入式的 Tomcat ，否则在 Tomcat4E 会出现问题；若使用 Main 函数启动，则不用排除 -->
12. [backcolor=transparent] [backcolor=transparent]<dependencies>
13. [backcolor=transparent]     [backcolor=transparent]<dependency>
14. [backcolor=transparent]         [backcolor=transparent]<groupId>[backcolor=transparent]org.springframework.boot[backcolor=transparent]</groupId>
15. [backcolor=transparent]         [backcolor=transparent]<artifactId>[backcolor=transparent]spring-boot-starter-web[backcolor=transparent]</artifactId>
16. [backcolor=transparent]         [backcolor=transparent]<exclusions>
17. [backcolor=transparent]             [backcolor=transparent]<exclusion>
18. [backcolor=transparent]                 [backcolor=transparent]<groupId>[backcolor=transparent]org.springframework.boot[backcolor=transparent]</groupId>
19. [backcolor=transparent]                 [backcolor=transparent]<artifactId>[backcolor=transparent]spring-boot-starter-tomcat[backcolor=transparent]</artifactId>
20. [backcolor=transparent]             [backcolor=transparent]</exclusion>
21. [backcolor=transparent]         [backcolor=transparent]</exclusions>
22. [backcolor=transparent]     [backcolor=transparent]</dependency>
23. [backcolor=transparent] [backcolor=transparent]</dependencies>
25. [backcolor=transparent] [backcolor=transparent]<!-- 添加 Spring Boot 插件 -->
27. [backcolor=transparent] [backcolor=transparent]<plugins>
28. [backcolor=transparent]     [backcolor=transparent]<plugin>
29. [backcolor=transparent]         [backcolor=transparent]<groupId>[backcolor=transparent]org.springframework.boot[backcolor=transparent]</groupId>
30. [backcolor=transparent]         [backcolor=transparent]<artifactId>[backcolor=transparent]spring-boot-maven-plugin[backcolor=transparent]</artifactId>
31. [backcolor=transparent]     [backcolor=transparent]</plugin>
32. [backcolor=transparent] [backcolor=transparent]</plugins>

[backcolor=transparent]注意：
在 pom.xml 里面引入的 Spring Boot 依赖，若要以 WAR 包形式在 Tomcat 中运行，需要排除 spring-boot-starter-web 嵌入式 Tomcat 依赖，否则会和 Tomcat 默认的 lib 内容形成冲突，导致项目无法启动。如果在 Main 函数中启动则不用排除嵌入式 Tomcat，但是在打包发布时，请一定记住需要排除。
创建 ServletInitializer 类，继承 SpringBootServletInitializer。
类似初始化 Spring 上下文，标记该项目打包成 WAR 项目在 Tomcat 中运行。
继承 SpringBootServletInitializer 类，实现 configure 方法 ServletInitializer.class。

1. [backcolor=transparent] [backcolor=transparent]public[backcolor=transparent] [backcolor=transparent]class[backcolor=transparent] [backcolor=transparent]ServletInitializer[backcolor=transparent] [backcolor=transparent]extends[backcolor=transparent] [backcolor=transparent]SpringBootServletInitializer[backcolor=transparent] [backcolor=transparent]{
3. [backcolor=transparent]     [backcolor=transparent]@Override
4. [backcolor=transparent]     [backcolor=transparent]protected[backcolor=transparent] [backcolor=transparent]SpringApplicationBuilder[backcolor=transparent] configure[backcolor=transparent]([backcolor=transparent]SpringApplicationBuilder[backcolor=transparent] application[backcolor=transparent])[backcolor=transparent] [backcolor=transparent]{
5. [backcolor=transparent]         [backcolor=transparent]return[backcolor=transparent] application[backcolor=transparent].[backcolor=transparent]sources[backcolor=transparent]([backcolor=transparent]StartupDemoApplication[backcolor=transparent].[backcolor=transparent]class[backcolor=transparent]);
6. [backcolor=transparent]     [backcolor=transparent]}
7. [backcolor=transparent] [backcolor=transparent]}

创建 Spring Boot 启动类。
类名：StartupDemoApplication.class

1. [backcolor=transparent] [backcolor=transparent]@SpringBootApplication
2. [backcolor=transparent] [backcolor=transparent]public[backcolor=transparent] [backcolor=transparent]class[backcolor=transparent] [backcolor=transparent]StartupDemoApplication[backcolor=transparent] [backcolor=transparent]{
4. [backcolor=transparent]     [backcolor=transparent]public[backcolor=transparent] [backcolor=transparent]static[backcolor=transparent] [backcolor=transparent]void[backcolor=transparent] main[backcolor=transparent]([backcolor=transparent]String[backcolor=transparent][][backcolor=transparent] args[backcolor=transparent])[backcolor=transparent] [backcolor=transparent]{
5. [backcolor=transparent]         [backcolor=transparent]//启动服务
6. [backcolor=transparent]         [backcolor=transparent]SpringApplication[backcolor=transparent].[backcolor=transparent]run[backcolor=transparent]([backcolor=transparent]StartupDemoApplication[backcolor=transparent].[backcolor=transparent]class[backcolor=transparent],[backcolor=transparent] args[backcolor=transparent]);
7. [backcolor=transparent]     [backcolor=transparent]}
8. [backcolor=transparent] [backcolor=transparent]}

删除 webapp 下面的 web.xml 文件。
若该文件存在，在容器加载 Web 的时候，就会直接加载该配置文件，但是由于该配置文件没有做任何配置，因此会造成 Spring Boot 加载不成功。
[backcolor=transparent]排除方式：
若发现发布在 EDAS 中的 WAR 没有执行您自己的代码，那么有可能就是该问题导致，请及时检查是否存在 web.xml 文件。
打包 WAR，上传 EDAS 启动即可。
如果测试阶段，需要直接在 Main 方法中运行，请把 pom.xml 文件中的 spring-boot-starter-tomcat 排除取消。

Spring Boot 结合 HSF 开发
