Question

我正在尝试使用wsdl:fault，但无法生成预期的java类（异常）。我生成的类（删除了注释和getter / setter）：

public class ProjectException extends Exception {
    private com.home.project.generated.Fault fault;
}

public class Fault {
    protected String errorMessage;
    protected long errorCode;
}

我期望获得的课程：

public class ProjectException extends Exception {
    protected String errorMessage;
    protected long errorCode;
}

我的wsdl：

如何直接在课堂中内联属性？

Answer 1

据我所知，你无法实现产生你期望的效果。

根据规范JAX-WS 2.1 http://download.oracle.com/otndocs/jcp/jaxws-2.1-mrel2-eval-oth-JSpec/，映射的错误需要包含故障bean的异常。使用实现规范的工具将始终为您提供一个使用@WebFault注释的包含Java Fault bean的Exception包装器。

Answer 2

请找到一种使用JAX-WS故障处理和异常处理来设置Web服务的方法。

根据您的需要，我使用 @WebFault 注释：

网络服务界面：

package foo.bar;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface MyProjectService {

    @WebMethod
    public String createProject(String name) throws ProjectException;
}

带有错误的Web服务实现：

在这里，我们根据项目名称模拟异常。

package foo.bar;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService(serviceName="MyProjectService", portName="MyProjectServiceService")
public class MyProjectServiceImpl implements MyProjectService {

    public MyProjectServiceImpl() {
    }

    @WebMethod  
    public String createProject(@WebParam(name="name") String name) throws ProjectException {
        if (name.equalsIgnoreCase("bad name")) {
            ProjectFault fault = new ProjectFault();
            fault.setFaultCode("123");
            fault.setFaultString("Custom error message");
            throw new ProjectException("123","Custom error message");
        } else {
            return "Project created : " + name;
        }
    }
}

ProjectFault bean：

JAXB运行时需要ProjectFault类来处理异常。

package foo.bar;

public class ProjectFault {

     private String faultCode;
     private String faultString;

    public String getFaultCode() {
        return faultCode;
    }

    public void setFaultCode(String faultCode) {
        this.faultCode = faultCode;
    }

    public String getFaultString() {
        return faultString;
    }

    public void setFaultString(String faultString) {
        this.faultString = faultString;
    }
}

您的自定义异常：ProjectException

此类需要使用@WebFault批注进行批注。

package foo.bar;

import javax.xml.ws.WebFault;

@WebFault(name="ProjectFault")
public class ProjectException extends Exception {

    private ProjectFault fault;

    public ProjectException() {
    }

    protected ProjectException(ProjectFault fault) {
        super(fault.getFaultString()); 
        this.fault = fault;
     }

    public ProjectException(String message, ProjectFault faultInfo){
        super(message);
        this.fault = faultInfo;
    }

    public ProjectException(String message, ProjectFault faultInfo, Throwable cause){
        super(message,cause);
        this.fault = faultInfo;
    }

    public ProjectFault getFaultInfo(){
        return fault;
    }

    public ProjectException(String message) {
        super(message);
    }

    public ProjectException(String code, String message) {
        super(message);
        this.fault = new ProjectFault();
        this.fault.setFaultString(message);
        this.fault.setFaultCode(code);
    }

    public ProjectException(Throwable cause) {
        super(cause);
    }

    public ProjectException(String message, Throwable cause) {
        super(message, cause);
    }
}

最后一步是生成WSDL并调整此示例。
