基于注释的Spring / JAX-RS集成，没有web.xml [英] Annotation based Spring / JAX-RS integration with no web.xml
问题描述
我正在尝试制作一个没有web.xml的Servlet 3.0 REST服务器，即仅依赖于java类和注释。我不确定如何同时使用Spring和servlet映射注册Resource类。
I'm trying to make a Servlet 3.0 REST server with no web.xml, ie dependent on java classes and annotations only. I'm not exactly sure how I can simultaneously register a Resource class with Spring and with the servlet mappings.
我目前有：
public class ApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer
{
@Override
protected Class<?>[] getRootConfigClasses()
{
return new Class<?>[]{RootConfiguration.class};
}
@Override
protected Class<?>[] getServletConfigClasses()
{
return new Class<?>[]{RestServletConfiguration.class};
}
@Override
protected String[] getServletMappings()
{
return new String[] {"/*"};
}
}
@Configuration
@ComponentScan({"com.my.spring.beans",
"com.my.spring.services"})
public class RootConfiguration
{
}
@Configuration
@ComponentScan("com.my.resource.classes")
public class RestServletConfiguration
{
}
当我开始应用程序，spring bean正确连接，但我不知道如何正确设置JAX-RS servlet过滤器。我目前正在使用Jersey，并且在网上没有找到很多关于将Jersey与Spring集成而不使用web.xml的信息。
When I start the application, the spring beans are wired correctly, but I'm not sure how to proceed with getting the JAX-RS servlet filter set up correctly. I am currently using Jersey, and haven't been able to find much on the web about integrating Jersey with Spring without using a web.xml.
有谁知道怎么做以这种方式将Jersey与Spring集成在一起？
Does anyone know how to integrate Jersey with Spring in this way?
推荐答案
您可以在无XML模式下集成Spring和Jersey。
You can integrate Spring and Jersey in a XML-less mode.
您需要扩展类 com.sun.jersey.spi.spring.container.servlet.SpringServlet 。例如：
package org.test;
import com.sun.jersey.spi.spring.container.servlet.SpringServlet;
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
@WebServlet(urlPatterns = {"/rest/*"}, initParams = {
@WebInitParam(name = "com.sun.jersey.config.property.packages",
value = "org.test.rest")})
public class JerseyServlet extends SpringServlet {
}
实际上，它是一个servlet。参数 com.sun.jersey.config.property.packages 表示扫描资源的位置（带注释的类 @Path ）。
Actually, it is a servlet. The parameter com.sun.jersey.config.property.packages indicates where scanning the resources (classes with annotation @Path).
以下代码是资源示例：
package org.test.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.test.service.DummyService;
@Path("test")
@Component
public class TestResource {
@Autowired
private DummyService service;
@GET
public String test() {
return service.sayHello();
}
}
此类资源需要扫描依赖注入的春天。例如：
Such resources need to be scanned by Spring for dependency injection. e.g.:
package org.test.rest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan("org.test.rest")
public class RestConfiguration {
}
此配置可由初始化程序类加载。例如：
And this configuration can be loaded by the initializer class. e.g.:
package org.test;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import org.test.rest.RestConfiguration;
import org.test.service.ServiceConfiguration;
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{ServiceConfiguration.class, RestConfiguration.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[]{};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
