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() {
    }
}
