无法访问Tomcat上部署的WAR文件

Question

我有一个Spring启动Rest服务项目，它在我的本地机器上工作。当我运行应用程序为"Spring Boot App"

我可以通过转到访问rest服务

http://127.0.0.1:8080/persons/all

它返回JSON，因为它应该。

我换了pom。xml打包到war，然后我创建了一个war，作为-

war文件名为“myapp-0.0.1-SNAPSHOT.war”，上传后，我试图通过访问

http://myserverip:8080/myapp-0.0.1-SNAPSHOT/persons/all

但我有一个404错误

我做错了什么？

我的pom。xml

当我构建应用程序时，我得到以下日志

我的MyappApplication.java

package com.mycompany;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class MyappApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyappApplication.class, args);
    }
}

Answer 1

将Spring引导可执行jar更改为可部署战的检查列表。

>

更换pom中的包装。xml从“jar”到“war”

正如kuhajeyan提到的，标记您的嵌入式tomcat依赖，如pom.xml.中提供的

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

让您的主Spring引导应用程序类像这样扩展SpringBootServlet初始工具

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
 }
}

从文件中

Answer 2

如果您将jar更改为Spring引导的战争，请添加以下依赖项

 <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>

Answer 3

请参阅：打包可执行jar和war文件

正如注释中提到的，您可以通过将war部署到独立的tomcat实例来部署Spring Boot应用程序。您需要对MyappApplication进行一些更改。java类，该类具有main（）方法。

>

使您的MyappApplication扩展SpringBootServlet初始器并覆盖其confiure（）方法，

@SpringBootApplication
public class MyappApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyappApplication.class, args);
    }

}

下一步是将打包为war，而不是您已经拥有的默认jar。

最后在您的pom中。xml将嵌入式tomcat容器的作用域更改为提供的，以便在部署到单独实例时不会发生冲突。
