eclipse下springboot打包war包

1. 修改package内容为war文件

<packaging>war</packaging>

2.配置servlet

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
    <scope>provided</scope> 
</dependency>

3.移除嵌入式tomcat插件

<exclusions> 
    <exclusion>                 
            <groupId>org.springframework.boot</groupId> 
        <artifactId>spring-boot-starter-tomcat</artifactId> 
    </exclusion> 
</exclusions>   

4.修改启动类，继承SpringBootServletInitializer类, 新增configure方法

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.support.SpringBootServletInitializer;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@MapperScan("com.example.mapper")//与dao层的@Mapper二选一写上即可(主要作用是扫包)
public class UserPerson4Application extends SpringBootServletInitializer{
    public static void main(String[] args) {
        SpringApplication.run(UserPerson4Application.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
       // 注意这里要指向原先用main方法执行的Application启动类
       return builder.sources(UserPerson4Application.class);
    }
}

5.右键项目->properties->Maven删除pom.xml,apply and close

6.右键项目，clean

6.右键项目，Maven build

7.Goals处填package，Skip Tests前面打勾

8.JRE选项里面选择JDK，Apply->Run

9.生成的war包在项目下的target目录里面
