java - 零星的 "Bean property is not readable or has an invalid getter method"错误

Question

我偶尔会收到以下错误。重新启动 Tomcat 服务器 (v7.0) 可以解决问题，但它会在一周左右后再次出现。

这些是观察结果:

1. “Bean 属性‘id’不可读或具有无效的 getter 方法:getter 的返回类型是否与 setter 的参数类型匹配？”

2. “id”字段用 @Id 注释，具有有效的 getter/setter 并且服务器重启会在短时间内“修复”错误。

关于导致此问题的原因或为什么重启可以暂时解决问题的任何想法？

其他详细信息:

}

AbstractBaseEntity 没有任何对 id 或与 id 相关的方法的引用:

@MappedSuperclass
public abstract class AbstractBaseEntity<ID extends Serializable> implements Serializable, Identifiable<ID>  {

}

ID 类:

@Embeddable
public class StltPK implements Serializable{

抱歉，如果这是信息过载，请尝试提供适量的信息以帮助解决此问题!谢谢

再次编辑以包含 JSP:

    <jsp:root version="2.1" xmlns:jsp="http://java.sun.com/JSP/Page"
        xmlns:form="http://www.springframework.org/tags/form">
  <form:form commandName="stlt" method="POST" action="${ctx}/stlt/save" id="stltEditForm">

    <form:hidden path="id.companyCode" />
    <form:hidden path="id.contractCode" />
    <form:hidden path="id.vendorCode" />
    ...
    </jsp:root>

Controller 正在填充 JSP(如果需要我可以添加更多？)

model.addAttribute("stlt", stlt);

pom.xml:

<dependency>
    <artifactId>spring-beans</artifactId>
    <groupId>org.springframework</groupId>
    <version>${spring.version}</version>
</dependency>

Spring 版本:

<spring.version>3.1.0.RELEASE</spring.version>

您可能遇到了这个错误:

https://jira.springsource.org/browse/SPR-9059

另见:

http://forum.spring.io/forum/spring-projects/container/112929-concurrent-problem-with-beanwrapperimpl-getpropertyvalue-in-3-1

上面的错误被认为是 SPR-8347 的重复，它被认为在 3.1.1 中得到修复
