基本概念

目前发现很多Java项目都是直接使用Maven作项目管理，在Maven中配置依赖，比如Spring boot完成操作，在经历了这么多操作后，还发现大家喜欢把Maven项目打包为war包，在此记录下，Maven创建spring boot项目，打包为war包！

代码与实例

程序结构如下：

这里最关键的就是porn.xml这个文件，打包成war包的地方：

填写spring boot的入口类：

还要添加一个依赖管理：

随后就是两大类，一个是依赖，一个是构建，构建里面要有插件：

<!--构建的时候要使用--><build><finalName>JSPDemo</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring-boot.version}</version><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-war-plugin</artifactId><version>2.4</version><configuration><failOnMissingWebXml>false</failOnMissingWebXml></configuration></plugin></plugins><resources><resource><directory>src/main/resources</directory><filtering>true</filtering></resource></resources></build>

这里要注意设置这个：

不然会报如下错误：

下面是tomcat的设置：

这里把war包导进去：

这里war包是这样产生的！

写一个测试，看看能不能成功:

断点如下：

程序结构如下：

源码如下：

Test.java

package com.jsp.server.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.GetMapping;@Controllerpublic class Test {@GetMapping("/Test")public String test(){return "Hello World!";}}

MainApplication.java

package com.jsp.server;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.web.support.SpringBootServletInitializer;@SpringBootApplicationpublic class MainApplication extends SpringBootServletInitializer {public static void main(String[] args){SpringApplication.run(MainApplication.class, args);}}

application.properties
