- 将SpringBoot的项目的打包方式设置为war
<groupId>com.example</groupId>
<artifactId>demo</artifactId>
<version>1.0.0</version>
<packaging>war</packaging>
- 移除内嵌的tomcat模块，但是为了我们在本机测试方便，我们还需要引入它，所以配置如下
<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>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
- 添加tomcat-servelt-api依赖
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-servlet-api</artifactId>
<version>7.0.42</version>
<scope>provided</scope>
</dependency>
- 修改入口方法 继承一个SpringBootServletInitializer类，并且覆盖configure方法
package com.example;
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.cache.annotation.EnableCaching;
@SpringBootApplication
@EnableCaching
public class SpringDataJpaExampleApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringDataJpaExampleApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SpringDataJpaExampleApplication.class, args);
}
}
- 添加war插件，用来自定义打包以后的war包的名称
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<warSourceExcludes>src/main/resources/**</warSourceExcludes>
<warName>springboot</warName>
</configuration>
</plugin>
引入上面这个插件，是避免maven打包的时候为我们默认的一个带有版本号的war包名称，因为我们部署到tomcat以后，在访问项目的时候，需要用到这个war包的名称
