Springboot配置图片虚拟映射示例代码

1.新建一个MyWebAppConfigurer 配置静态资源需要映射的位置、建议把addResourceLocations的路径写在application.yml中、方面以后部署的打包修改配置文件的时候做外部配置文件加载、方面修改。这边为了节约时间就在代码中写了。


package io.renren.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**

//springboot 2.x配置
@Configuration
public class MyWebAppConfigurer implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/image/**").addResourceLocations("file:C:\Users\Administrator\Desktop\11月毕设\");
    }
}

2.没有加权限控制的话直接通过IP+端口+项目名以及addResourceHandler中的路径就可以访问了、有权限控制的话需要权限放心或放在static静态资源文件夹下。个人用的shiro权限、所以需要放行。


 @Bean("shiroFilter")
    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();
        shiroFilter.setSecurityManager(securityManager);
        //oauth过滤
        Map<String, Filter> filters = new HashMap<>();
        filters.put("oauth2", new OAuth2Filter());
        shiroFilter.setFilters(filters);
        Map<String, String> filterMap = new LinkedHashMap<>();
        filterMap.put("/webjars/**", "anon");
        filterMap.put("/druid/**", "anon");
        filterMap.put("/app/**", "anon");
        filterMap.put("/sys/login", "anon");
        filterMap.put("/swagger/**", "anon");
        filterMap.put("/v2/api-docs", "anon");
        filterMap.put("/swagger-ui.html", "anon");
        filterMap.put("/swagger-resources/**", "anon");
        filterMap.put("/captcha.jpg", "anon");
        filterMap.put("/image/**", "anon");
        filterMap.put("/**", "oauth2");
        shiroFilter.setFilterChainDefinitionMap(filterMap);
        return shiroFilter;
    }
