tomcat不能访问服务器中带中文的静态资源问题

如何解决请求地址存在中文出现400异常？

1.tomcat8升级为tomcat9，可能会导致中文问题。需要在conf/server.xml加URIEncoding="UTF-8"配置。具体如下。

2.加了之后发现还是不行，几经辗转，发现是shiro由1.6升级到1.7导致的，解决方案如下。

2.1自定义CustomShiroFilterFactoryBean，继承原来的ShiroFilterFactoryBean。

package com.***.***;

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.InvalidRequestFilter;
import org.apache.shiro.web.filter.mgt.DefaultFilter;
import org.apache.shiro.web.filter.mgt.FilterChainManager;

import javax.servlet.Filter;
import java.util.Map;

/**

 * @author ruoyi
 */
public class CustomShiroFilterFactoryBean extends ShiroFilterFactoryBean {

    @Override
    protected FilterChainManager createFilterChainManager() {
        FilterChainManager manager = super.createFilterChainManager();
        // URL携带中文400，servletPath中文校验bug
        Map filterMap = manager.getFilters();
        Filter invalidRequestFilter = filterMap.get(DefaultFilter.invalidRequest.name());
        if (invalidRequestFilter instanceof InvalidRequestFilter) {
            ((InvalidRequestFilter) invalidRequestFilter).setBlockNonAscii(false);
        }
        return manager;
    }
}

2.2修改spring-content-shiro.xml文件中过滤器的地址，将org.apache.shiro.spring.web.ShiroFilterFactoryBean 修改为上面自己定义的类
