- 关于cxf resutful 中出现No resource classes found的问题
-
用cxf开发restful服务，出现以下问题，希望大家能给予帮助，在此先谢过。Caused by: org.apache.cxf.service.factory.ServiceConstructionException at org.apache.cxf.jaxrs.JAXRSServerFactoryBean.create(JAXRSServerFactoryBean.java:219) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeCustomInitMethod(AbstractAutowireCapableBeanFactory.java:1706) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1645) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1574) ... 62 more Caused by: org.apache.cxf.service.factory.ServiceConstructionException: No resource classes found at org.apache.cxf.jaxrs.AbstractJAXRSFactoryBean.checkResources(AbstractJAXRSFactoryBean.java:317) at org.apache.cxf.jaxrs.JAXRSServerFactoryBean.create(JAXRSServerFactoryBean.java:159) ... 69 more
解决方案
CXF中，出现 No services have been found.
Android出错问题：AndroidManifest.xml:2: error: No resource identifier found for attribute 'installLocatio
error: No resource identifier found for attribute 问题
解决方案二：
我的配置如下：
（1）、web.xml
<?xml version="1.0" encoding="UTF-8"?>

解决方案四：
（3）、HelloWS接口
package org.github.mervyn.webServices_CXF_springRestful;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
public interface IHelloWS {
@GET
@Path("/HelloWS/{id}")
@Consumes(MediaType.APPLICATION_JSON)
@Produces({MediaType.APPLICATION_JSON,"text/html; charset=UTF-8"})
String getUserById(@PathParam("id")int id);
}
解决方案五：
（4）、HelloWSImpl
package org.github.mervyn.webServices_CXF_springRestful;
import java.io.IOException;
import java.io.StringWriter;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.codehaus.jackson.JsonFactory;
import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.map.ObjectMapper;
public class HelloWSImpl implements IHelloWS {
@Override
/*@GET
@Path("/HelloWS/{id}")
//@Consumes(MediaType.APPLICATION_JSON)
@Produces({MediaType.APPLICATION_JSON,"text/html; charset=UTF-8"})*/
public String getUserById(@PathParam("id")int id){
System.out.println("id为： " + id);
User user = new User();
user.setId(id);
user.setName("mervyn");
ObjectMapper mapper = new ObjectMapper();
StringWriter sw = new StringWriter();
JsonGenerator gen = null;
try {
gen = new JsonFactory().createJsonGenerator(sw);
mapper.writeValue(gen, user);
gen.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String json = sw.toString();
return json;
}
}
解决方案六：
（5）cxf-server.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">
<import resource="classpath*:META-INF/cxf/cxf.xml" />
<import resource="classpath*:META-INF/cxf/cxf-servlet.xml" />
<bean id="helloWSImpl" class="org.github.mervyn.webServices_CXF_springRestful.HelloWSImpl" />
<jaxrs:server id="iHelloWS" address="/">
<jaxrs:serviceBeans>
<ref bean="helloWSImpl"/>
</jaxrs:serviceBeans>
</jaxrs:server>
</beans>
解决方案七：
问题已解决。是因为自己粗心。cxf实现restful风格的web services 接口上写上注解，同时也要在接口的实现类中添加上相应的注解。
