我有 cxf restFul 生成 spring:

        Personel personel = new Personel(personCode);
        return personel;
    }
}

我UserManager.java

package com.restWS;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import com.model.Personel;

    @GET
    @Path("/hello")
    public Personel getPersonelByPersonCode(String personCode);
}

personel.java

package com.model;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

import org.apache.cxf.aegis.type.java5.XmlElement;
import org.springframework.beans.factory.annotation.Autowired;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "Personel")
public class Personel implements Serializable {
    private String nationalCode;
    private String name;
    private String lastName;
    private String fatherName;

    public Personel(String personCode) {
        this.name = "reza";
        this.lastName = "ramezani matin";
        this.fatherName = "ali";
        this.nationalCode = "3980020827";
    }

    public String getNationalCode() {
        return nationalCode;
    }

    public void setNationalCode(String nationalCode) {
        this.nationalCode = nationalCode;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getFatherName() {
        return fatherName;
    }

    public void setFatherName(String fatherName) {
        this.fatherName = fatherName;
    }

}

以上项目在weblogic 12.1.1部署成功。当 firefox 发送请求时请求为“http://localhost:7001/restfulWS-0.0.1-SNAPSHOT/services/rest/UserManager/personelService/hello/10”，有效负载：未找到响应的消息正文编写器class 人员已登录控制台

Answer 1

你需要告诉服务器这个 web 方法将生成一个 xml 输出你可以通过添加这一行来做到这一点，尝试通过删除 class 级别生成标签

 @GET
 @Path("/hello/{personCode}")
 @Produces("application/xml") //added this line ,you can declare anything json/xml
 public Personel getPersonelByPersonCode(@PathParam("personCode") String personCode) {
     Personel personel = new Personel(personCode);
     return personel;
 }

您还需要使用 xml 标签来注释您的人员 class

@XmlElement(name="nationalCode")
private String nationalCode;

@XmlElement(name="name")
private String name;

@XmlElement(name="lastName")
private String lastName;

@XmlElement(name="fatherName")
private String fatherName;

注解可以跳过，但它给了你自定义标签的权力（例如"firstName"可以用作"fName"标签）

希望对您有所帮助！

祝你好运！
