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;
}
}
}
