简单的测试;
配置pom文件下载源:在项目下右键选择maven,选择open “setting.xml”,将下面内容复制粘贴即可:
<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository.

- 快速体验web开发(domain和web的使用):第3课
对json的友好支持;
请求传参;
数据校验;
自定义的Filter;
自定义的Property;
遇到的问题:单元测试中如果出现如下错误,则表示测试文件与main文件的目录不对应。

解决方案:在写单元测试时,测试的文件与main文件目录相同,如下:
- Spring Data JPA的使用(repository的使用):第4课
上手JPA;
