步骤:
1.实现 WebMvcConfigurer 配置类
2.实现拦截器
3.将拦截器添加到配置中
4.添加需要拦截的请求
5.添加需要排除的请求
java
package com.zp.springbootdemo.interceptor;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configurationpublic class WebMvcConfig implements WebMvcConfigurer {
@Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new MyInterceptor()) .addPathPatterns(/**) .excludePathPatterns(/exclude/**); }}
步骤:
1.实现WebMvcConfigurer配置类
2.实现拦截器 3
. 把拦截器添加到配置中
4.添加需要拦截的请求
5.添加需要排除的请求
package com.zp.springbootdemo.interceptor; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; /** * 和springmvc的webmvc拦截配置一样 * @author zp */ @Configuration public class WebConfigurer implements WebMvcConfigurer { /** * 拦截器配置 * @param registry */ @Override public void addInterceptors(InterceptorRegistry registry) { // addPathPatterns拦截所有请求,excludePathPatterns排除特殊的请求 //registry.addInterceptor(LoginInterceptor()).addPathPatterns("/**"); registry.addInterceptor(AuthorityInterceptor()).addPathPatterns("/**"); //excludePathPatterns 排除的请求 // registry.addInterceptor(LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/user/**"); // registry.addInterceptor(AuthorityInterceptor()).addPathPatterns("/**").excludePathPatterns("/user/**"); } /** * 拦截器一 * @return */ @Bean public LoginInterceptor LoginInterceptor() { return new LoginInterceptor(); } /** * 拦截器二 * @return */ @Bean public AuthorityInterceptor AuthorityInterceptor() { return new AuthorityInterceptor(); } }
基于URL实现的拦截器:
package com.zp.springbootdemo.interceptor; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.127.0.0.1:8080/user/getUser?token=123
结果:
基于注解的拦截器
①创建注解:
package com.zp.springbootdemo.interceptor; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; /** * 在需要登录验证的Controller的方法上使用此注解 */ @Target({ElementType.METHOD})// 可用在方法名上 @Retention(RetentionPolicy.RUNTIME)// 运行时有效 public @interface LoginRequired { }
②创建拦截器:
package com.zp.springbootdemo.interceptor; import org.springframework.web.method.HandlerMethod; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.127.0.0.1:8080/user/getUser?token=123
结果:
测试接口代码2:
package com.zp.springbootdemo.system.controller; import com.zp.springbootdemo.interceptor.LoginRequired; import com.zp.springbootdemo.system.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import java.util.Map; @RestController @RequestMapping("/user") public class UserController { @Autowired private UserService userService; @GetMapping("/getUser") @LoginRequired public Map<String,String> getUser(@RequestParam Map<String,String> user){ return userService.getUser(user); } }
请求地址:
127.0.0.1:8080/user/getUser?token=123
结果:
