【shiro】shiro升级1.7以上版本url请求报400的问题（提示“HTTP状态 400 - 错误的请求”）

shift，查询好久资料才找到。

Shiro版本升级到1.7及以上版本后，新增了对非ASCII字符的校验，主要涉及到InvalidRequestFilter类中的blockNonAscii属性。当该属性设置为true时（这是默认值），Shiro会拦截任何包含非ASCII字符的请求，从而导致400错误。

我是老springmvc项目，

在xml中配置

	<bean id="invalidRequestFilter" class="org.apache.shiro.web.filter.InvalidRequestFilter">
		<property name="blockNonAscii" value="false" /> <!-- 允许非ASCII字符通过 -->
	</bean>

和

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
    <property name="securityManager" ref="securityManager"/>
    <property name="filterChainDefinitions">
        <value>
            /statics/**=anon
            /files/**=anon
            /captcha.jpg=anon
            /**=authc
        </value>
    </property>
    <!-- 配置过滤器，应用 InvalidRequestFilter -->
    <property name="filters">
        <map>
            <entry key="invalidRequest" value-ref="invalidRequestFilter" />
        </map>
    </property>
</bean>

就可以了

springboot项目的话，在Spring配置中注入一个自定义的InvalidRequestFilter实例，并设置blockNonAscii属性为false

@Bean
public InvalidRequestFilter invalidRequestFilter() {
    InvalidRequestFilter invalidRequestFilter = new InvalidRequestFilter();
    invalidRequestFilter.setBlockNonAscii(false); 
    return invalidRequestFilter;
}

@Bean
public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {
    ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
    factoryBean.setSecurityManager(securityManager);
    // 添加自定义的InvalidRequestFilter
    factoryBean.setFilters(new HashMap<String, Filter>() {{
        put(DefaultFilter.invalidRequest.name, invalidRequestFilter());
    }});
    return factoryBean;
}
