maven如下：

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.62</version> </dependency>

構造如下的類：

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; }

生成好對象后

然后直接返回這個o，就可以在前端得到json數據了！
