#### 把fastjson换成最新版本就好了 ####

替换之前
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>fastjson</artifactId>
                <version>1.2.20</version>
            </dependency>
    替换后
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>fastjson</artifactId>
                <version>1.2.54</version>
            </dependency>
     替换成最新版本，就好了
     一定要确认好对应依赖版本
