@Controller返回json

使用@ResponseBody或者返回ResponseEntity类

@Controller 返回string 默认是返回view的名字，想要直接返回json则需要@ResponseBody

    @GetMapping("/map")
    @ResponseBody
    public java.util.Map<String,String> test(){
        java.util.Map<String,String> map = new HashMap<>();
        map.put("hello","hello");
        return map;
    }

@RestController返回页面

@RestController默认返回json，想要返回页面则需要方法体返回ModelAndView

    @GetMapping("foo")
    public ModelAndView foo(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("foo/index");
        return modelAndView;
    }

permitAll()是不受保护的（也就是无需登录即可访问的）

xadd myStream * field1 value1

命令讲解 xadd myStream * field1 value1

这个命令看起来像是使用xadd命令向Redis流数据结构（Stream）中添加数据。下面是对这个命令的解释：

xadd: xadd是Redis的一个命令，用于向Stream数据结构中添加新的条目。
myStream: myStream是指定的Stream名称，表示将要向哪个Stream添加数据。
*: *表示新的条目的ID将由Redis自动生成。Redis会为每个条目生成一个唯一的ID，可以用来标识该条目。
field1: field1是Stream中的字段名称，表示将要添加的数据的字段名称。
value1: value1是要添加到field1字段中的值。
综合起来，这个命令的作用是向名为myStream的Stream中添加一条新的数据，该数据包含一个字段field1，字段值为value1，并由Redis自动生成一个唯一的ID作为条目的ID。

@RequiredArgsConstructor 和 @Qualifier(“beanName”) 组合不生效

/api/** 和/api/*的区别是什么？

在 Spring MVC 中，/api/** 和 /api/* 是两种不同的 URL 路径匹配模式，它们之间有一些区别：

/api/**：表示匹配以 /api/ 开头的任何路径，包括子路径。例如，/api/user、/api/user/details、/api/user/profile 等路径都会被匹配到。

/api/*：表示匹配以 /api/ 开头的一级路径，不包括子路径。也就是说，只有直接以 /api/ 后面跟着一个路径时才会被匹配到。例如，/api/user 会被匹配到，但/api/user/details、/api/user/profile 等路径不会被匹配到。

因此，/api/** 匹配更加灵活，可以匹配多级路径，而 /api/* 只能匹配一级路径。根据具体的需求和 URL 结构，您可以选择使用其中一种路径匹配模式来定义请求映射。

server.servlet.context-path和spring.mvc.servlet.path

server.servlet.context-path=/context-path
spring.mvc.servlet.path=/servlet-path

Then the application servlet path will become http://localhost:8080/context-path/servlet-path.
