外置tomcat映射服务器路径以及springboot内置tom

外置tomcat映射路径

在tomcat里的conf下的server.xml里Host标签下加入

<Context docBase="D:\pdf\" path="report" reloadable="true"  />

其中的docBase就是磁盘映射路径，path为访问路径，比如localhost:8080/report就可以访问到d盘pdf文件夹下的静态文件

springboot 1.x内置映射路径方法

继承org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
重写addResourceHandlers方法，其中report为访问路径，后面为文件映射绝对路径，file开头代表是一个文件位置绝对路径。

package cn.ways.gtids.common.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.validation.beanvalidation.MethodValidationPostProcessor;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import cn.ways.util.PropertiesUtils;


@Configuration
public class Config extends WebMvcConfigurerAdapter {
    
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {        
        /**
         * 资源映射路径
         * addResourceHandler：访问映射路径
         * addResourceLocations：资源绝对路径
         */
        registry.addResourceHandler("/report/**").addResourceLocations("file:D:/pdf/");
    }
}

springboot 2.x内置映射路径方法

实现WebMvcConfigurer

@Configuration
public class WebMvcConfig implements WebMvcConfigurer{
 
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/report/**").addResourceLocations("file:D:/pdf/");
    }
}

springboot默认静态资源访问配置

@Configuration
@EnableWebMvc
public class StaticResourceConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
          registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }

}
