15、SpringMVC进行json交互

由 ε祈祈猫儿з 提交于 2019-12-07 10:54:26
SpringMVC进行json交互 json数据格式在接口调用中、html页面中较常用，json格式比较简单，解析还比较方便。 请求json、输出json。要求请求的是json串，前端页面中需要将请求的内容转成json，不太方便。 请求key/value、输出json。此方法比较常用。 环境准备 添加json转换的依赖 <!-- json 转换--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.7.2</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> 查看依赖树 [INFO] +- com.fasterxml.jackson.core:jackson-databind:jar:2.7.2:compile [INFO] | +- com.fasterxml.jackson.core:jackson-annotations:jar:2.7.0
