SpringBoot打war包

1.修改pom.xml文件

//第一处
<packaging>war</packaging>

//添加依赖
<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web</artifactId>
			<exclusions>
				<exclusion>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-tomcat</artifactId>
		 		</exclusion>
			</exclusions>
</dependency>

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
</dependency>

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-legacy</artifactId>
       <version>1.1.0.RELEASE</version>
</dependency>

2.方法主入口修改
【继承SpringBootServletInitializer，实现configure()方法】

//直接给出列子
package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
@MapperScan({"com.example.demo.mysqlDao","com.example.demo.oracleDao"})
public class OraMysServerApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(OraMysServerApplication.class, args);
    }

    //打war包修改，需要继承SpringBootServletInitializer
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(OraMysServerApplication.class);
    }
}

3.如果有web.xml文件按下面修改（没有就不用修改）
复制下面的代码，修改com.yzker.test.application.Application为你自己的启动类

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.yzker.test.application.Application</param-value>
      </context-param>

      <listener>
        <listener-class>org.springframework.boot.legacy.context.web.SpringBootContextLoaderListener</listener-class>
      </listener>

      <!--
          <filter>
              <filter-name>metricFilter</filter-name>
              <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
          </filter>

          <filter-mapping>
              <filter-name>metricFilter</filter-name>
              <url-pattern>/*</url-pattern>
          </filter-mapping>
      -->

      <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextAttribute</param-name>
          <param-value>org.springframework.web.context.WebApplicationContext.ROOT</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
      </servlet>

      <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
</web-app>

到此为止，就可以了，如有问题请评论。
