这个错误提示是因为在调用 `com.example.mybatisplusspringboot.exception.RestExceptionHandler.handleMethodArgumentNotValid` 方法时,Spring MVC 框架无法解析第二个参数的值。可能是因为该参数没有被正确注入或者注入的值不符合要求。你可以检查一下代码,确认第二个参数是否正确注入,并且是否符合 HttpHeaders 类型的要求。此外,你还可以尝试在该方法上添加 `@ModelAttribute` 注解,以确保参数正确注入。

使用spring验证框架方法的参数必须不加BindingResult 验证失败抛出java.lang.IllegalStateException: Could not resolve parameter [1] in
Controller方法中使用Spring验证框架时,如果方法参数中带有BindingResult参数,那么验证失败时不会抛出异常,而是会将错误信息存储在BindingResult中返回给前端。如果方法参数中没有BindingResult参数,则验证失败时会抛出异常。
所以,回答你的问题:使用Spring验证框架方法的参数必须不加BindingResult。如果你希望在验证失败时抛出异常,可以在方法参数中不加BindingResult,然后在方法体内手动抛出异常。例如:
```java
@PostMapping("/user")
public void addUser(@Valid User user) {
// do something
if (bindingResult.hasErrors()) {
throw new IllegalStateException("Validation failed: " + bindingResult.getAllErrors());
}
}
```
java.lang.illegalstateexception: could not load cacheawarecontextloaderdelegate [class org.springframework.test.context.cache.defaultcacheawarecontextloaderdelegate]
这个错误是因为在Spring框架中,缓存感知的上下文加载器委托不可用,导致无法加载。可能是因为您的Spring配置文件中有错误,或者是因为您使用的Spring版本不受支持。建议检查您的配置文件和Spring版本,并尝试解决问题。
