Example 1 with SentinelWebInterceptor

use of com.alibaba.csp.sentinel.adapter.spring.webmvc.SentinelWebInterceptor in project Sentinel by alibaba.

the class InterceptorConfig method addSpringMvcInterceptor.

private void addSpringMvcInterceptor(InterceptorRegistry registry) {
    SentinelWebMvcConfig config = new SentinelWebMvcConfig();
    // Depending on your situation, you can choose to process the BlockException via
    // the BlockExceptionHandler or throw it directly, then handle it
    // in Spring web global exception handler.
    // config.setBlockExceptionHandler((request, response, e) -> { throw e; });
    // Use the default handler.
    config.setBlockExceptionHandler(new DefaultBlockExceptionHandler());
    // Custom configuration if necessary
    config.setHttpMethodSpecify(true);
    // By default web context is true, means that unify web context(i.e. use the default context name),
    // in most scenarios that's enough, and it could reduce the memory footprint.
    // If set it to false, entrance contexts will be separated by different URLs,
    // which is useful to support "chain" relation flow strategy.
    // We can change it and view different result in `Resource Chain` menu of dashboard.
    config.setWebContextUnify(true);
    config.setOriginParser(request -> request.getHeader("S-user"));
    // Add sentinel interceptor
    registry.addInterceptor(new SentinelWebInterceptor(config)).addPathPatterns("/**");
}

Example 3 with SentinelWebInterceptor

use of com.alibaba.csp.sentinel.adapter.spring.webmvc.SentinelWebInterceptor in project ddf-common by dongfangding.

the class SentinelAutoConfiguration method addSpringMvcInterceptor.

/**
 * 接口请求后会被拦截到控制台的---簇点链路上， 可以不适用@SentinelResource注解， 区别是， 如果接口调用链上没有生命是的@SentinelResource资源，
 * 那么就将最外层接口入口层（即方法的@RequestMapping）作为资源且不会往下生成资源链。而如果@RequestMapping方法调用了某个@SentinelResource资源，
 * 则会在入口层往下生成资源链路
 * <p>
 * 格式如下
 * 无资源映射
 * /helloA
 * <p>
 * 有资源映射
 * /helloB
 * -- hello(如果这个方法声明了@SentinelResource的话)
 *
 * @param registry
