在Spring Security 3.05中配置并发时出现以下错误。我正在使用Tomcat 7.我已经遵循了Spring Security文档，无法理解为什么会出现此错误。

答案 0 :(得分：3)
我认为错误消息非常具有描述性：
在[...] org.springframework.beans中定义名为'concurrencyFilter'的bean时出错。 ConversionNotSupportedException ：无法转换类型的属性值'java.lang.String'为 property'sessionRegistry '所需的类型'org.springframework.security.core.session。 SessionRegistry ';嵌套异常是java.lang.IllegalStateException：无法将类型[java.lang.String]的值转换为属性'sessionRegistry'所需的类型[org.springframework.security.core.session.SessionRegistry]：找不到匹配的编辑器或转换策略
看起来你所要做的就是改变：
<beans:property name="sessionRegistry" value="sessionRegistry"/>
为：
<beans:property name="sessionRegistry" ref="sessionRegistry"/>
