明天计划的事情：
完成其他controller编写，实现基础的增删改查功能
遇到的问题：
对角色表和角色模块关联表的操作不太理解，问过师兄后基本了解了，明天尝试编写代码实现相关功能。
收获：
1.对postman的使用比之前熟练了。
2.@PathVariable：接收请求路径中占位符的值
3.@ResponseBody的作用是将java对象转为json格式的数据
将controller的方法返回的对象通过适当的转换器转换为指定的格式之后，写入到response对象的body区，通常用来返回JSON数据或者是XML数据。
在使用 @RequestMapping后，返回值通常解析为跳转路径，但是加上 @ResponseBody 后返回结果不会被解析为跳转路径，而是直接写入 HTTP response body 中。 比如异步获取 json 数据，加上 @ResponseBody 后，会直接返回 json 数据。@RequestBody 将 HTTP 请求正文插入方法中，使用适合的 HttpMessageConverter 将请求体写入某个对象。
