application.porperties中的配置不生效导致改端口后不生效原因,无法加载resource下的资源文件

springboot项目新建后,application.porperties文件放置路径为/springboot01/src/main/resources

但更改端口后

server.port=8081

server.context-path=/springboot01

hello=\u6211\u7231\u4F60

jdbc.url=jdbc://mysql:localhost11

jdbc.username=root

jdbc.password=sa

jdbc.driver=com.mysql.driver

启动仍是8080端口

经过查各种资料,问题得以解决,解决方案为:

第一种办法:

把/springboot01/src/main/resources路径下的application.porperties放置根目录下,即可成功启动。

第二种办法:

Java Build Path ->Source->Excluded置为None

第三种办法

重写WebMvcConfigurerAdapter的addResourceHandlers方法

package com.sm.app;

import org.springframework.context.annotation.Configuration;

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

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

@Configuration

public class WebConfig extends WebMvcConfigurerAdapter {

@Override

    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        registry.addResourceHandler("/**").addResourceLocations("classpath:/");

        super.addResourceHandlers(registry);

    }

}

三种方法,最终我是用第二种方法解决的,搜了好多资料,最终整理到这些
