SpringBoot部署到外部Tomcat的配置

1、修改pom.xml文件

①设置打包形式

<packaging>war</packaging>

②移除嵌入式Tomcat插件

修改前:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
</dependency>

修改后:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
  <!-- 移除嵌入式tomcat插件 -->
  <exclusions>
    <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
    </exclusion>
  </exclusions>
</dependency>

③添加servlet-api依赖

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

2、修改Application启动类

修改前:

@SpringBootApplication
public class KlausApplication {
  public static void main(String[] args) {
    SpringApplication.run(KlausApplication.class, args);
  }
}

修改后:


@SpringBootApplication
public class KlausApplication extends SpringBootServletInitializer {
  public static void main(String[] args) {
    SpringApplication.run(KlausApplication.class, args);
  }
  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(KlausApplication.class);
  }
}

3、将war包放入外部tomcat的webapps下

4、在外部Tomcat的bin目录下双击startup.bat

5、访问方式:输入http://localhost:8989/项目名称/接口地址

问题描述:SpringBoot项目部署到Tomcat中访问接口出现404
问题原因:地址输入时项目名称不是tomcat中部署的war包名称
解决方法:修改问题地址
问题地址:http://localhost:8080/nbs/
成功地址:http://localhost:8080/nbs-0.0.1-SNAPSHOT/
