spring----@ResponseBody注解

自动将数据封装成json格式的数据返回回去

Maven

        <!-- Json Begin -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
        </dependency>
 <!-- Json End -->

　　

如果不需要摸个字段被打包的话

使用@JsonIgnore注解get方法上

前提必须有这个依赖(上面已经有了)

 <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
</dependency>
