今天学习如何配置spring cloud 安全认证,发现一个错误,错误的信息如下:

关键信息是:Can't configure anyRequest after itself

产生原因,我引用的代码为:

@EnableWebSecurity
    static class WebSecurityConfigure extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // 在/eureka/**端点忽略csrf验证
            http.csrf().ignoringAntMatchers("/eureka/**");
            // 配置使请求需要通过httpBasic或form验证
            http.authorizeRequests().anyRequest()
                    .authenticated()
                    .and()
                    .formLogin()
                    .and()
                    .httpBasic();
            super.configure(http);
        }
    }

这是一个网上spring cloud的代码示例,示例代码使用的spring cloud版本是 2.0.1,而我在环境中使用spring 版本是2.2.1(Hoxton.RELEASE)。

原因是:anyRequest 多次被调用,所以将多余的anyRequest去掉即可。

---- 我检查了下代码,没有发现有anyRequest被多次调用,是不是代码内部的多次调用呢?所幸注销掉,代码可以顺利跑起来。
