我关注this rather simple tutorial但由于某种原因,我无法访问我创建的资源/word-embeddings/hello
,以便测试它是否在Eclipse中工作。但是,我可以通过运行mvn tomcat7:run
从终端运行它,但为什么这不适用于Eclipse?
我没有对教程做过很多更改,所以这里是代码:
AppConfig.java
package org.ema.server.spring.config;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "org.ema.server.spring")
public class AppConfig {
}
AppInitializer.java
package org.ema.server.spring.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class[] getRootConfigClasses() {
return new Class[] { AppConfig.class };
}
@Override
protected Class[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
WordEmbeddingsRestController.java
package org.ema.server.spring.controller;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class WordEmbeddingsRestController {
@GetMapping("/word-embeddings/hello")
public ResponseEntity<String> getHello() {
return new ResponseEntity<String>("Hello", HttpStatus.OK);
}
}
最后但并非最不重要的是 pom.xml
<?xml version="1.0"?>
<project

当我运行Tomcat服务器并尝试访问http://localhost:8080/ema/word-embeddings/hello
时,我登陆404页面。
知道为什么会这样吗?
注意:我在AppInitializer
中设置了一些断点,以检查这些方法是否被调用,但是,这似乎并非如此,所以看起来整个Spring工具链根本没有被执行。
这是我启动Tomcat 8服务器时收到的完整日志:
