关于java：不推荐使用WebMvcConfigurerAdapter类型

The type WebMvcConfigurerAdapter is deprecated

我只是迁移到Spring MVC版本5.0.1.RELEASE，但突然在Eclipse STS中将WebMvcConfigurerAdapter标记为已弃用

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/");
}
....
}

我该如何删除！

从Spring 5开始，您只需要实现接口WebMvcConfigurer：

1	public class MvcConfig implements WebMvcConfigurer {

这是因为Java 8在覆盖WebMvcConfigurerAdapter类功能的接口上引入了默认方法

看这里：

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html

相关讨论

如今，我一直在开发名为Springfox的Swagger等效文档库，发现在Spring 5.0.8(目前正在运行)中，接口WebMvcConfigurer已由类WebMvcConfigurationSupport类实现，我们可以直接对其进行扩展。

import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

public class WebConfig extends WebMvcConfigurationSupport { }

这就是我用来设置资源处理机制的方式，如下所示：

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");

registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}

使用org.springframework.web.servlet.config.annotation.WebMvcConfigurer

使用Spring Boot 2.1.4.RELEASE(Spring Framework 5.1.6.RELEASE)时，请像这样

@Override

configurer.enable();
}

}

在春季，每个请求都将通过DispatcherServlet。为了避免通过DispatcherServlet(Front contoller)请求静态文件，我们配置了MVC静态内容。

春天3.1。引入了ResourceHandlerRegistry，以配置ResourceHttpRequestHandlers以便从类路径，WAR或文件系统中提供静态资源。我们可以在Web上下文配置类中以编程方式配置ResourceHandlerRegistry。

we have added the /js/** pattern to the ResourceHandler, lets include the foo.js resource located in the webapp/js/ directory

we have added the /resources/static/** pattern to the ResourceHandler, lets include the foo.html resource located in the webapp/resources/ directory

@Configuration

public class StaticResourceConfiguration implements WebMvcConfigurer {

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
System.out.println("WebMvcConfigurer - addResourceHandlers() function get loaded...");
registry.addResourceHandler("/resources/static/**")
.addResourceLocations("/resources/");

registry
.addResourceHandler("/js/**")
.addResourceLocations("/js/")
.setCachePeriod(3600)
.resourceChain(true)
.addResolver(new GzipResourceResolver())
.addResolver(new PathResourceResolver());
}
}

XML配置

<mvc:annotation-driven />
<mvc:resources mapping="/staticFiles/path/**" location="/staticFilesFolder/js/"
cache-period="60"/>

如果文件位于WAR的webapp / resources文件夹中，则为Spring Boot MVC静态内容。

1	spring.mvc.static-path-pattern=/resources/static/**
