一个方法获取所有Controller接口信息

项目上需要导出所有接口方法上自定义注解中的值，犯了难。一般我们都是通过fIlter,inteceptor,aop中拦截请求进而可以获取的类的信息。这样可能需要调用多次才能得到我们要的数据。这次给大家分享一下可以一次性获取的方案。不多说，直接上代码：

@Controller
@RequestMapping(value = "/api")
public class TestController {

    @Autowired
    private WebApplicationContext applicationContext;

    @ResponseBody
    @RequestMapping(value = "/getAllUrl", method = RequestMethod.GET)
    public List getAllUrl() {
        RequestMappingHandlerMapping mapping = applicationContext.getBean(RequestMappingHandlerMapping.class);
        // 获取url与类和方法的对应信息
        Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();

        List<Map<String, String>> list = new ArrayList<Map<String, String>>();
        for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {
            Map<String, String> map1 = new HashMap<String, String>();
            RequestMappingInfo info = m.getKey();
            HandlerMethod method = m.getValue();
            //获取当前方法所在类名
            Class<?> bean = method.getBeanType();
            //获取方法上注解以及注解值
            OperationLog methodAnnotation = method.getMethodAnnotation(OperationLog.class);
            if(methodAnnotation==null){
                continue;
            }
            String privilegeName = methodAnnotation.tag()+"_"+methodAnnotation.type();
            PatternsRequestCondition p = info.getPatternsCondition();
            for (String url : p.getPatterns()) {
                map1.put("url", url);
            }
            map1.put("className", method.getMethod().getDeclaringClass().getName()); // 类名
            map1.put("method", method.getMethod().getName()); // 方法名
            map1.put("tag", privilegeName);
            list.add(map1);
        }
        return list;
    }

}
