java - RESTEasy - 简单的字符串数组/集合编码

Question

在 RESTEasy 中是否有一种简单的编码和解码 String[] 或 List 的方法？

我的代码示例:

@GET
@Path("/getSomething")
@Produces(MediaType.APPLICATION_JSON)
public List<String> getSomeData() {
    return Arrays.asList("a","b","c","d");

}

上面给了我一个异常(exception):

Could not find MessageBodyWriter for response object 
of type: java.util.Arrays$ArrayList of media type: application/json

你可能需要这样包装它:

public List<JaxbString> getList(){
     List<JaxbString> ret= new ArrayList<JaxbString>();
     List<String> list = Array.asList("a","b","c");
          for(String s:list){
              ret.add(new JaxbString(s));
          }
     return ret;
}

@XmlRootElement
public class JaxbString {

    private String value;

    public JaxbString(){}

    public JaxbString(String v){
        this.setValue(v);
    }

    public void setValue(String value) {
        this.value = value;
    }

    @XmlElement
    public String getValue() {
        return value;
    }

}
