大家都知道springmvc是JaveWeb里最流行的mvc框架,swagger也是最流行的文档生成工具,两个最流行的结合起来也只需要仅仅几分钟而已

#index.html
swagger-ui-2.1.3这个文件夹是从https://github.com/swagger-api/swagger-ui项目中的dist文件夹拷贝过来的,想要最新版可以自己拷贝,还要改之前mvc-dispatcher-servlet.xml中地址转发的文件名
index.html这个文件在swagger-ui-2.1.3文件夹下,只需要改默认的url,该项目在35行左右,改为地址:端口/项目名/v2/api-docs
示例
// 这里填项目地址最后以v2/api-docs结尾
// 因为我是用idea跑的,所以8080/不用加项目名,真正部署是需要加的
url = "http://localhost:8080/v2/api-docs";

#TestController 这个controller用来测试,只展示最简单的用法,详细请看swagger文档
@Api(value = "测试API", description = "测试API")
@RestController
@RequestMapping("/test")
public class TestController {
@RequestMapping(value = "/hello")
public String hello(String name) {
return "hello "+name;
}
}
