Question

我开始使用Java和休息服务，我使用GET方法创建了一个休息服务，这个方法返回一个带有他的属性的UserVO，我使用setMethods设置属性值和随机值并返回对象但这不能将映射对象映射到json球衣我使用tomcat 6，JDK 1.8.0_121和eclipse并显示此错误：

com.sun.jersey.spi.container.ContainerResponse write
GRAVE: A message body writer for Java class Autoconsulta.ValueObject.UsuarioVO, and Java type class Autoconsulta.ValueObject.UsuarioVO, and MIME media type application/json was not found.
The registered message body writers compatible with the MIME media type are:
application/json ->
  com.sun.jersey.json.impl.provider.entity.JSONJAXBElementProvider$App
  com.sun.jersey.json.impl.provider.entity.JSONArrayProvider$App
  com.sun.jersey.json.impl.provider.entity.JSONObjectProvider$App
  com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider$App
  com.sun.jersey.json.impl.provider.entity.JSONListElementProvider$App

VO

public class UsuarioVO {

    private String rut;
    private boolean isValid;

    public String getRut() {
        return rut;
    }
    public void setRut(String rut) {
        this.rut = rut;
    }
    public boolean isValid() {
        return isValid;
    }
    public void setValid(boolean isValid) {
        this.isValid = isValid;
    }

}

我的服务：

@GET
@Path("/getUser")
@Produces({MediaType.APPLICATION_JSON})
public UsuarioVO getUsuario() {

    UsuarioVO u = new UsuarioVO();
    u.setRut("123444");
    u.setValid(true);

    return u;
}
