maven如下：

   	
    
     com.alibaba
    	
    
     fastjson
    	
    
     1.2.62
    
   

构造如下的类：

package com.xxxx.xxxx.object;import lombok.Data;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.Id;import javax.persistence.Table;@Entity@Data@Table(name = "xxx_areaxxx")public class XXXAreasecXXXX {    @Id    @Column(name = "XXXXXXXXXX")    private String XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private String XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private String XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private String XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private String XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Float XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Integer XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Integer XXXXXXXXXX;    @Column(name = "XXXXXXXXXX")    private Integer XXXXXXXXXX;}

生成好对象后

然后直接返回这个o，就可以在前端得到json数据了！
