<dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
 </dependency>

升级为

 <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.10.0</version>
 </dependency>

之后，之前的下载文件接口直接报错，找了半天的问题，是因为我的接口中参数包含中文
如：

image.png

fileName是中文所以直接在ShiroFilterFactoryBean层就报错了
处理方式：

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;
public class CustomShiroFilterFactoryBean extends ShiroFilterFactoryBean {
    @Override
    protected FilterChainManager createFilterChainManager() {
        FilterChainManager manager = super.createFilterChainManager();
        Map<String, Filter> filterMap = manager.getFilters();
        Filter invalidRequestFilter = filterMap.get(DefaultFilter.invalidRequest.name());
        if (invalidRequestFilter instanceof InvalidRequestFilter) {
            //此处是关键，设置false跳过URL携带中文400，servletPath中文校验
            ((InvalidRequestFilter) invalidRequestFilter).setBlockNonAscii(false);
        }
        return manager;
    }
}
