这个需要后台提供服务的接口负责的事情~~

使用registerJsonValueProcessor来执行输出内容的转换

public class MyObject {
    private String name="";
    private byte[] content;
    private String title="";
    private Long id;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public byte[] getContent() {
        return content;
    }
    public void setContent(byte[] content) {
        this.content = content;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
}

public class JSONConfTest {

    public static void main(String[] args) {
        List<MyObject> dt=new ArrayList<MyObject>();

            somMyObject.setName("name"+i);
            somMyObject.setTitle("title"+i);
            try {

                }
            }
        });
       
        config.registerJsonValueProcessor(byte[].class, new JsonValueProcessor() {  
            @Override

        JSONArray dtsJSONArray = JSONArray.fromObject(dt, config);
