Question

我重新创建一个spring boot简单项目＆＃34; greetings＆＃34;，当我运行它在服务器上时，它工作，我在浏览器中获取JSON数据，如下所示：

本地主机：9090 / API /问候

它显示：

[{＆＃34; id＆＃34;：1，＆＃34; text＆＃34;：＆＃34; Hello world1＆＃34;}，{＆＃34; id＆＃34;：2，＆＃ 34;文字＆＃34;：＆＃34; Hello world2＆＃34;}]

我通过控制台成功生成war文件：

... \ workspace-sts-3.8.0.RELEASE \ demo＆gt; mvn clean install

我已经在我的ubuntu服务器上安装了tomcat7 14.04 tls，

并抛出Web管理器我选择要在服务器上部署的war文件：

但是当点按网址以显示所有问候语时，它不会显示任何内容：

error : the requested resource type is not valid

所以我检查tomcat 7 catalina.out日志中的错误：

信息：部署Web应用程序存档/var/lib/tomcat7/webapps/demo-0.0.1-SNAPSHOT.war 2016年7月28日下午7:38:55 org.apache.catalina.loader.WebappClassLoader validateJarFile 信息：validateJarFile（/var/lib/tomcat7/webapps/demo-0.0.1-SNAPSHOT/WEB-INF/lib/javax.el-3.0.0.jar） - jar未加载。请参见Servlet规范3.0，第10.7.2节。违规类：javax / el / Expression.class 2016年7月28日下午7:38:55 org.apache.catalina.loader.WebappClassLoader validateJarFile 信息：validateJarFile（/var/lib/tomcat7/webapps/demo-0.0.1-SNAPSHOT/WEB-INF/lib/javax.servlet-api-3.1.0.jar） - jar未加载。请参见Servlet规范3.0，第10.7.2节。违规类：javax / servlet / Servlet.class 2016年7月28日下午7:38:55 org.apache.catalina.loader.WebappClassLoader validateJarFile 信息：validateJarFile（/var/lib/tomcat7/webapps/demo-0.0.1-SNAPSHOT/WEB-INF/lib/tomcat-embed-el-8.0.36.jar） - 未加载jar。请参见Servlet规范3.0，第10.7.2节。违规类：javax / el / Expression.class

但我确实不明白究竟是什么问题，

这是我的项目结构：

project structure

这是我的java类：

1 / class DemoApplication

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
      @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(DemoApplication.class);
        }
 }

2 / class Greeting

public class Greeting {

    private BigInteger id;
    private String text;

    public BigInteger getId() {
        return id;
    }
    public void setId(BigInteger id) {
        this.id = id;
    }
    public String getText() {
        return text;
    }
    public void setText(String text) {
        this.text = text;
    }

}

3 / class GreetingController

@RestController
public class GreetingController {

    private static BigInteger nextId;
    private static Map<BigInteger, Greeting> greetingMap;

    private static Greeting save(Greeting greeting){
        if(greetingMap == null){
            greetingMap  = new HashMap<BigInteger, Greeting>();
            nextId = BigInteger.ONE;
        }


        //if update....
        if(greeting.getId() != null){
            Greeting oldGreeting = greetingMap.get(greeting.getId());
            if(oldGreeting == null){
                return null;
            }
            greetingMap.remove(greeting.getId());
            greetingMap.put(greeting.getId(), greeting);

            return greeting;
        }

        // if create....
        greeting.setId(nextId);
        nextId = nextId.add(BigInteger.ONE);
        greetingMap.put(greeting.getId(), greeting);

        return greeting;
    }


    static {
        Greeting g1 = new Greeting();
        g1.setText("Hello word");
        save(g1);

        Greeting g2 = new Greeting();
        g2.setText("Hello samsa");
        save(g2);   
    }

    @RequestMapping(
            value="/api/greetings", 
            method=RequestMethod.GET, 
            produces=MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Collection<Greeting>> getGreetings(){

        Collection<Greeting> greetings = greetingMap.values();      
        return new ResponseEntity<Collection<Greeting>>(greetings, HttpStatus.OK);


    }

    @RequestMapping(
            value="/api/greetings/{id}", 
            method=RequestMethod.GET, 
            produces=MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Greeting> getGreeting(@PathVariable("id") BigInteger id){
        Greeting greeting = greetingMap.get(id);
        if(greeting == null){
            return new ResponseEntity<Greeting>(greeting, HttpStatus.NOT_FOUND);
        }

        return new ResponseEntity<Greeting>(greeting, HttpStatus.OK);

    }


    @RequestMapping(
            value="/api/greetings", 
            method=RequestMethod.POST, 
            consumes=MediaType.APPLICATION_JSON_VALUE,
            produces=MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Greeting> createGreeting(@RequestBody Greeting greeting){

        Greeting savedGreeting = save(greeting);
        return new ResponseEntity<Greeting>(savedGreeting, HttpStatus.CREATED);

    }



    @RequestMapping(
            value="/api/greetings/{id}", 
            method=RequestMethod.PUT, 
            consumes=MediaType.APPLICATION_JSON_VALUE,
            produces=MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Greeting> updateGreeting(@RequestBody Greeting greeting){

        Greeting updatedGreeting = save(greeting);
        if(updatedGreeting == null){
            return new ResponseEntity<Greeting>(HttpStatus.INTERNAL_SERVER_ERROR);
        }
        return new ResponseEntity<Greeting>(updatedGreeting, HttpStatus.OK);

    }


    private static boolean delete(BigInteger id) {
          Greeting deletedGreeding = greetingMap.remove(id);
          if(deletedGreeding == null){
              return false;
          }
          return true;
    }

    @RequestMapping(
            value="/api/greetings/{id}", 
            method=RequestMethod.DELETE, 
            consumes=MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Greeting> deletedGreeting(@PathVariable("id") BigInteger id, @RequestBody Greeting greeting){

        boolean deleted = delete(id);
        if(!deleted){
            return new ResponseEntity<Greeting>(HttpStatus.INTERNAL_SERVER_ERROR);
        }

        return new ResponseEntity<Greeting>(HttpStatus.NO_CONTENT);
    }

}

Answer 1

您可能没有在application.properties上设置上下文路径，因此Tomcat正在使用应用程序名称的默认路径。

将server.contextPath=/添加到属性文件以设置嵌入式tomcat的上下文路径，并为外部tomcat将 context.xml 以及以下内容添加到项目中以设置上下文路径。

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/"/>
