你现在截图里的接口是：

/applet/getRandom?mobilePhone=15290161737

最可疑的是：你新配置里把 /aplet/** 或 /applet/** 从 userInterceptor 的排除项删掉了，而且 probationInterceptor 也从 /**/*.do 改成了 /**，所以 /applet/getRandom 这种接口现在也会被拦截。下面这版会把每个拦截器进入、返回 true/false、状态码、是否已提交响应都打印出来，方便你直接看是哪个拦截器返回了 false。

你可以直接整体替换 MywebConfig.java。

启动后重新请求：

text
http://localhost:8086/applet/getRandom?mobilePhone=15290161737

然后你重点看控制台有没有类似：

text
!!!!!!!!!! [UserInterceptor] 返回 false，请重点检查这个拦截器 !!!!!!!!!!

或者：

text
!!!!!!!!!! [ProbationInterceptor] 返回 false，请重点检查这个拦截器 !!!!!!!!!!

从你现在这份配置看，大概率是 UserInterceptor 或 ProbationInterceptor 把 /applet/getRandom 拦住了。如果确认是它们导致的，恢复接口返回数据时，建议把这两个地方都加上：

java
"/applet/**"

也就是：

java
registry.addInterceptor(logInterceptor("UserInterceptor", userInterceptor))
        .addPathPatterns("/**")
        .excludePathPatterns(
                ...
                "/applet/**",
                ...
        );

以及：

java
registry.addInterceptor(logInterceptor("ProbationInterceptor", probationInterceptor))
        .addPathPatterns("/**")
        .excludePathPatterns(
                ...
                "/applet/**",
                ...
        );
