Eclipse中springboot打war包

1、修改pom.xml，添加如下：(重点是【 <packaging>war</packaging>】)

    <artifactId>vulSystem</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>war</packaging>

2、移除tomcat依赖（操作依旧在pom.xml中）
代码如下：

        <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>

当然这一步操作也可以更改为：添加spring-boot-starter-tomcat依赖，scope设置为provided
替代的带入如下：

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

3、让启动类继承SpringBootServletInitializer，并重写config方法，代码如下：

package cn.ihep;

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;

/**
 * SpringBoot启动类
 * 
 * @author xiaoming
 *
 */
@SpringBootApplication
@MapperScan("cn.ihep.dao")
public class ApplicationEntrace extends SpringBootServletInitializer {
    public static void main(String[] args) {
        System.out.println("启动springboot");
        SpringApplication.run(ApplicationEntrace.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builders) {
        return builders.sources(ApplicationEntrace.class);
    }
}

4、项目右键：

• run as ----->Maven clean

• run as ------>Maven build
  另外，请在Goals中写上：clean install ，如下图：

  
  runas

顺利的话，会在target目录下生成.war包。
【当然，我在Maven build的时候就出现很多jar包找不到的情况，但都是由于pom.xml文件中配置依赖的时候把<scope>test</scope>给加进去了，把它删除就Ok了】
