### spring boot项目从零开始-集成身份验证 ###

*  步骤
 *   *   *  MyFilterConfig.java
         *  MyIamFilter.java
 *  测试

# 步骤 #

主要通过拦截器来实现

### MyFilterConfig.java ###

package com.ydfind.start.config;
    
    import lombok.Getter;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Getter
    @Configuration
    public class MyFilterConfig {
    
        @Bean
        public FilterRegistrationBean filterRegistration() {
            FilterRegistrationBean registration = new FilterRegistrationBean(new MyIamFilter());
            registration.addUrlPatterns("/api/v1/*");
            registration.setName("urlFilter");
            return registration;
        }
    }

### MyIamFilter.java ###

package com.ydfind.start.config;
    
    import lombok.extern.slf4j.Slf4j;
    
    import javax.servlet.*;
    import javax.servlet.http.HttpServletRequest;
    import java.io.IOException;
    
    @Slf4j
    public class MyIamFilter implements Filter {
    
        @Override
        public void init(FilterConfig config) throws ServletException {
        }
    
        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
            // 这里可以进行身份校验
            HttpServletRequest req = (HttpServletRequest) request;
            String uri = req.getRequestURI();
            System.out.println("当前请求的是 = " + uri);
            // 验证通过，正常执行代码
            chain.doFilter(request, response);
        }
    
        @Override
        public void destroy() {
        }
    }
