不推荐使用WebMvcConfigurerAdapter类型 [英] The type WebMvcConfigurerAdapter is deprecated

问题描述

我只是迁移到spring mvc version 5.0.1.RELEASE 但是在eclipse中突然STS WebMvcConfigurerAdapter被标记为已弃用

I just migrate to spring mvc version 5.0.1.RELEASE but suddenly in eclipse STS WebMvcConfigurerAdapter is marked as deprecated

public class MvcConfig extends WebMvcConfigurerAdapter {
  @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
        // to serve static .html pages...
        registry.addResourceHandler("/static/**").addResourceLocations("/resources/static/");
    }
  ....
  }

我怎么能删除这个！

推荐答案

从Spring 5开始，你只需要实现接口 WebMvcConfigurer ：

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

这是因为Java 8在接口上引入了默认方法，涵盖了 WebMvcConfigurerAdapter 类

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class
