无法将战争部署到雄猫

Question

我有spring引导应用程序，当我用spring引导运行它时，它可以工作，但是当我构建war并将其部署到tomcat时，我得到404状态

我将这些行从spring docs添加到maven:

<properties>
<start-class>com.example.deploytest.DeploytestApplication</start-class>
</properties>
<packaging>war</packaging>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

这是我的主类:

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

和简单控制器:

@RestController
public class MainController {
@GetMapping
public String hello() {
return "hello world";
}
}

tomcat版本是10.0.27

怎么了?

Answer 1

pom.xml应该像这样:

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

如果没有，你也可以尝试在你的主类中添加SpringBootServletInitializer接口:

@SpringBootApplication
public class SpringBootTomcatApplication extends SpringBootServletInitializer {
}

Answer 2

尝试给你的GetMapping一个url

@GetMapping("/")

Answer 3

servlet API版本不匹配，尝试使用与嵌入式tomcat相同的版本
