Spring RESTful app基于Java的配置
我使用Spring RESTful应用程序并且工作正常。 Rest URL提供基于JSON的数据，并使用RequestMapping注释进行映射。在着陆网址[localhost:8080]中，我希望有一个带有一些信息的JSP页面index.jsp。我想用基于Java的注释做它并且它不起作用。我的意思是现在我甚至不会得到基于JSON的数据，除非将WebServletConfiguration文件删除。项目结构如下：
我提供了configuration文件夹中的文件
HelloWorldInitializer.java
public class HelloWorldInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { HelloWorldConfiguration.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
HelloWorldConfiguration.java
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springmvc")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
@Bean(name = "Views")
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/jsps/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
WebServletConfiguration.java
public class WebServletConfiguration implements WebApplicationInitializer {
public void onStartup(ServletContext ctx) throws ServletException {
AnnotationConfigWebApplicationContext webCtx = new AnnotationConfigWebApplicationContext();
webCtx.register(HelloWorldConfiguration.class);
webCtx.setServletContext(ctx);
ServletRegistration.Dynamic servlet = ctx.addServlet("dispatcher", new DispatcherServlet(webCtx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
我在控制台中收到了这个消息，

相关控制器呼叫在这里，
@RestController
public class HelloWorldRestController {
@Autowired
UserService userService; //Service which will do all data retrieval/manipulation work
@RequestMapping(value = "/", method = RequestMethod.GET)
public String showHome() {
return "index";
}
// some code
// ..........
// ..........
}
这是pom.xml文件，

现在，在目标网页和所有其他网址中，我都获得了Http 404 Error。
如何解决这个问题？

不应该将“HelloWorldConfiguration.class”传递给getServletConfigClasses吗？
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="CallManipulation.CallManipulation" android:versionCode="1" android:versionName="1.0">
<uses-sdk android:minSdkVersion="16" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<application android:label="CallManipulation">
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
</manifest>

问题是你没有@Controller类使用Spring Viewresolver返回一个视图，在本例中为index.jsp。
@RestContoller和@Controller的 @ResponseBody构成了HTTP响应的主体，通常是JSON或XML。这就是你将index视为字符串的原因。
