SpringBoot 部署war包

1.修改打包pom.xml配置

 

 <packaging>war</packaging>

 

 

 

2.移除嵌入式tomcat插件，在pom.xml的spring-boot-starter-web节点，添加如下代码

 

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

 

 

3.加servlet-api的依赖（可不添加）

 

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

 

 

4.通过maven定义项目名称

 

<build>
	<finalName>project name</finalName>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
                        <configuration>
	                    <executable>true</executable>
	                    <includeSystemScope>true</includeSystemScope>
                        </configuration>
		</plugin>
	</plugins>
</build>

 

 

   如果包含本地加载lib，添加一下节点

 

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-war-plugin</artifactId>
	<configuration>
		<warName>project name</warName>

 

		<webResources>
			<resource>
				<directory>src/main/resources/lib</directory>
				<targetPath>WEB-INF/lib</targetPath>
				<includes>
					<include>**/*.jar</include>
				</includes>
			</resource>
		</webResources>
	</configuration>
</plugin>

 

5.修改启动类，修改启动类，并重写configure方法。

我们需要类似于web.xml的配置方式来启动spring上下文了，在Application类的同级添加一个SpringBootStartApplication类，其代码如下:

 

/**
 * 修改启动类，继承 SpringBootServletInitializer 并重写 configure 方法
 */
public class SpringBootStartApplication extends SpringBootServletInitializer {
   public static void main( String[] args ){
       SpringApplication.run(SpringBootStartApplication .class, args);
   }

   /**
    *新增方法
    */
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
       // 注意这里要指向原先用main方法执行的SpringBootStartApplication 启动类
       return builder.sources(SpringBootStartApplication .class);
   }  
}
