Spring Boot教程第11篇：swagger2

swagger2学习

swagger,中文“拽”的意思。它是一个功能强大的api框架，它的集成非常简单，不仅提供了在线文档的查阅，而且还提供了在线文档的测试。另外swagger很容易构建restful风格的api，简单优雅帅气，正如它的名字。

    public String deleteUser(@PathVariable Long id) {
        books.remove(id);
        return "success";
    }

    @ApiIgnore//使用该注解忽略这个API
    @RequestMapping(value = "/hi", method = RequestMethod.GET)
    public String  jsonTest() {
        return " hi you!";
    }
}

Swagger2Application.java

@SpringBootApplication
public class Swagger2Application {
    public static void main(String[] args) {
        SpringApplication.run(Swagger2Application.class, args);
    }
}

总结

推荐swagger此种，比rest doc好在可以动态生成数据。
