使用fastjson時，對象轉json遇到的首字母大小寫問題

在使用fastjson進行數據類型轉換時發現，pojo類里面的屬性首字母大寫，在轉成json之后，變成了小寫。導致數據存儲一直有問題。

pom.xml

　　　　<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.28</version>
        </dependency>

 

解決方法：

 

        在pojo類的屬性get方法上加上你需要的key。

這樣轉換的json，對應的key就改變為你注解對應的屬性名。
