数据结构

后台系统开发接口返回数据

现在我们需要用后台系统来返回我们之前的json数据。

定义ItemCatResult

我们根据之前json的数据结构，我们来定义IteamCatResult:

定义ItemCatData

我们都把它们放在common里面：

并在common的pom.xml导入json的依赖：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.taotao.parent</groupId><artifactId>taotao-parent</artifactId><version>0.0.1-SNAPSHOT</version></parent><groupId>com.taotao-common</groupId><artifactId>taotao-common</artifactId><dependencies><!-- Jackson Json处理工具包 --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency></dependencies>
