java枚舉類型JSON格式返回處理

public enum  PositionParam {
    POSITION_PARAM1(1,"總經理"),
    POSITION_PARAM2(2,"銷售經理"),
    POSITION_PARAM3(3,"人力資源");

    private Integer code;
    private String name;

    private PositionParam(Integer code,String name){
        this.code=code;
        this.name=name;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

上面的枚舉類以JSON格式返給前臺後顯示的是

["POSITION_PARAM1","POSITION_PARAM2","POSITION_PARAM2"]

而實際想要得到的數據是

[{name:"總經理",code:1},{name:"銷售經理",code:2},{name:"人力資源",code:3}]

處理辦法：

引入jar依賴

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.60</version>
</dependency>

然後在枚舉類中加入以下註解

@JsonFormat(shape = JsonFormat.Shape.OBJECT)
