            result.getFieldErrors().forEach(error -> {
                System.out.print("field："+error.getField());
                System.out.println(" ==> message："+error.getDefaultMessage());

使用测试

 

localhost:8080/hello?productId=1&productName=apple&price=0

 

默认输出

2020-07-15 18:41:42.456  INFO 5484 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : Initializing Servlet 'dispatcherServlet'
2020-07-15 18:41:42.460  INFO 5484 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : Completed initialization in 4 ms
Product(productId=1, productName=apple, price=0.0)
field：price ==> message："商品价格不能低于0.01"

 

设置 header：Accept-Language en-US，控制台输出：

Product(productId=1, productName=apple, price=0.0)
field：price ==> message："price of product can not be less than 0.01"

国际化属性文件设置成功
