##SpingBoot下的WebArgumentResolver
参数解析器 需要集成类型WebArgumentResolver 并在@Configuration配置类型中配置参数解析器
import javax.servlet.http.HttpServletRequest; import org.springframework.core.MethodParameter; import org.springframework.web.bind.support.WebArgumentResolver; import org.springframework.web.context.request.NativeWebRequest; public class ArgumentResolver implements WebArgumentResolver { @Override public Object resolveArgument(MethodParameter methodParameter, NativeWebRequest webRequest) throws Exception { Class<?> parameterType = methodParameter.getParameterType(); if (parameterType != null) { HttpServletRequest request = webRequest.getNativeRequest(HttpServletRequest.class); if (parameterType.equals(User.class)) { return request.getAttribute(Constant.CURRENT_WX_USER_LOGIN); } } return UNRESOLVED; } } @Configuration public class WebConfig extends WebMvcConfigurationSupport { @Override public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) { argumentResolvers.add(new ServletWebArgumentResolverAdapter(new ArgumentResolver())); } }添加拦截器，并在配置文件中配置拦截器
import com.qf.common.constant.Constants; import com.qf.entity.dto.Admin; import org.apache.shiro.SecurityUtils; import org.springframework.web.method.HandlerMethod; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class PermissionInterceptor extends HandlerInterceptorAdapter { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { if (handler.getClass().isAssignableFrom(HandlerMethod.class)) { Admin admin = (Admin) SecurityUtils.getSubject().getPrincipal(); if (admin != null) { request.setAttribute(Constants.LOGIN_ADMIN, admin); } } return super.preHandle(request, response, handler); } } import com.qf.admin.interceptor.PermissionInterceptor; import com.qf.admin.resolver.ArgumentResolver; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.method.support.HandlerMethodArgumentResolver; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport; import org.springframework.web.servlet.mvc.method.annotation.ServletWebArgumentResolverAdapter; import java.util.List; @Configuration public class WebConfig extends WebMvcConfigurationSupport { @Bean public PermissionInterceptor permissionInterceptor() { return new PermissionInterceptor(); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(permissionInterceptor()) // 权限拦截器 .addPathPatterns("/**") // 拦截所有 .excludePathPatterns("/") // 排除拦截默认 .excludePathPatterns("/css/**") // 排除拦截静态资源 .excludePathPatterns("/js/**") // 排除拦截静态资源 .excludePathPatterns("/favicon.ico") // 排除拦截静态资源 .excludePathPatterns("/login"); // 排除拦截登录逻辑 super.addInterceptors(registry); } }
