com.sun.jersey.server.impl.application.WebApplicationImpl _handleRequest

Question

我正在構建一個JAX-RS項目，該項目使用配置文件重定向到我定義了HTTP方法的郵件類。 在調試時，控件轉到配置文件，如下所示：

package com.ODSResrcSysApp;

import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.core.Application;

public class ODSResrcSysConfig extends Application 
{
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<Class<?>>();
        classes.add(ODSResrcSysSvcREST.class);
        return classes;
    }
}

從這里開始，控件應該轉到ODSResrcSysSvcREST.class，其中uri模式的定義如下。

package com.ODSResrcSysApp;

import java.io.IOException;
import java.io.InputStream;
import java.sql.Clob;
import java.sql.ResultSet;
import java.util.Properties;

import javax.ws.rs.GET;
import javax.ws.rs.MatrixParam;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/*")
public class ODSResrcSysSvcREST 
{
    @GET
    @Path("/Test")
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public String gettstCon() throws WebApplicationException
    {
        System.out.println("Entering gettstCon method.");

        String result = null;
        ODSConnection odsconn = new ODSConnection();

        try
        {
            result = odsconn.connect();
            if(result == "connection successful")
            {
                result = "<ResourceSystem>Connection established successfully</ResourceSystem>";
            }
            else
            {
                result = "<Error>Error occured while establishing connection. If issues persists, contact CTS SOA team.</Error>";
            }
        }
        catch (Exception ex)
        {
            result = ex.getMessage().toString();
        }
        return result;
    }

}

此時出現以下錯誤：

不確定導致錯誤的是什么。 即使它使用相同的jar文件集，同一工作空間中的另一個JAX-RS項目也能正常工作。 通過代碼調試時我也會看到以下頁面：

DeferredResourceConfig.class

The source attachment does not contain the source fir the file DeferredResourceConfig.class .......

我的項目中包含的jar文件列表是：

 1.  asm-3.1.jar 
 2.  cloveretl.engine.jar 
 3.  commons-lang.jar 
 4.  ibm-wink-jaxrs.jar
 5.  jackson-core-asl-1.8.3.jar 
 6.  jackson-jaxrs-1.8.3.jar
 7.  jackson-mapper-asl-1.8.3.jar 
 8.  jackson-xc-1.8.3.jar
 9.  jersey-client-1.9.1.jar 
 10. jersey-core-1.9.1.jar 
 11. jersey-json-1.9.1.jar
 12. jersey-server-1.9.1.jar 
 13. jettison-1.1.jar 
 14. jsr311-api.jar
 15. jsr311-api-1.1.1.jar 
 16. madapi.jar 
 17. slf4j-api.jar

非常感謝您的回答。 先感謝您。

Answer 1

將@Path("/*")更改為@Path("/") 。 你可以給那里的正則表達*無效。
