### 今天的积累都是为了更好的明天，加油！我是java程序员，大家可以关注我一起学习哈！ ###

## ** springboot部署war包有两种情况：** ##

### 1.新建的springboot项目 ###

新建项目时，Packaging选war

新建之后，会发现pom文件里多了个spring-boot-starter-tomcat

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

还多了一个ServletInitializer继承了 SpringBootServletInitializer。

### 2.原有的springboot项目 ###

如果是原有的项目，就需要自己改造下了！

**pom文件改造：**

首先指定包为war

移除嵌入的tomcat

<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>

添加javax.servlet-api

<dependency>
    	<groupId>javax.servlet</groupId>
    	<artifactId>javax.servlet-api</artifactId>
    	<version>3.1.0</version>
    	<scope>provided</scope>
    </dependency>

指定war包名

<finalName>sliderverificationcode</finalName>

添加 maven-surefire-plugin

<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-surefire-plugin</artifactId>
    				<configuration>
    					<testFailureIgnore>true</testFailureIgnore>
    				</configuration>
    			</plugin>

**启动类改造：**

启动类继承SpringBootServletInitializer，重写configure方法！

@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(SliderverificationcodeApplication .class);
        }

通过命令mvn install -Dbuildnumber.phase=NONE打成war包

放到tomcat的webapps下！

**访问的路径**是http://localhost:IP:端口/项目名/接口，例如：http://localhost:8082/sliderverificationcode/index

到此改造完成！有问题欢迎留言！
