如果你想实现一些定制化功能,只需要写这个组件,然后将它交给springboot管理,springboot会给我们自动装配
以下是spring官方文档解释
由官方文档可知,想要自定义组件,需要实现以下步骤
示例:自定义视图解析器
package com.yl.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.View; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.ViewResolverRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; import java.util.Locale; /** * mvc配置类 */ @Configuration public class MyMvcConfig implements WebMvcConfigurer { /** * 将自定义视图解析器配置成bean存入spring */ @Bean public ViewResolver myViewResovler(){ return new MyViewResolver(); } /** * 自定义视图解析器,实现视图解析器接口 */ public static class MyViewResolver implements ViewResolver{ @Override public View resolveViewName(String viewName, Locale locale) throws Exception { return null; } } }
