在搭建springside4-master项目并测试功能时，遇到访问/task页面导致的500错误。错误源于JSP页面尝试访问Spring Data的Chunk接口中的`content`属性，该属性在旧版本中为抽象类的私有成员。通过对比不同版本的spring-data-jpa，发现在1.4.4.RELEASE版本中，PageImpl直接实现了Page接口，没有使用继承，从而避免了访问限制。将项目中spring-data-jpa版本降级为1.4.4.RELEASE后，问题得到解决。

springside4-master是一个开源的项目,前话就不说了,本文是写给在搭建springside4-master的人共同研究的.

经过一番痛苦,终于把项目跑起来了.

测了注册,登陆,修改,退出,管理员都没问题.

结果来到这个查看任务的例子   http://localhost:8080/task

后台报错如下:

严重: Servlet.service() for servlet [springServlet] in context with path [/quickstart] threw exception [An exception occurred processing JSP page /WEB-INF/views/task/taskList.jsp at line 28

25:     <table id="contentTable" class="table table-striped table-bordered table-condensed">

关键出错的代码己标出

<c:forEach items="${tasks.content}" var="task">
            <tr>
                <td><a href="${ctx}/task/update/${task.id}">${task.title}</a></td>
                <td><a href="${ctx}/task/delete/${task.id}">删除</a></td>
            </tr>
        </c:forEach>

这里用到了tasks.content

tasks是一个分页对象.

---------------------TaskService-------------------

    public Page<Task> getUserTask(Long userId, Map<String, Object> searchParams, int pageNumber, int pageSize,
            String sortType) {
        PageRequest pageRequest = buildPageRequest(pageNumber, pageSize, sortType);
        Specification<Task> spec = buildSpecification(userId, searchParams);

        return taskDao.findAll(spec, pageRequest);
    }

Page是一个接口,具体实现类如下 

----------------------org.springframework.data.domain.PageImpl        版本为spring-data-commons-1.8.0.RELEASE.jar-----------------------

public class PageImpl<T> extends Chunk<T> implements Page<T> {

    private static final long serialVersionUID = 867755909294344406L;

    private final long total;

在这里还看不到我们要的List <T> content

在父类Chunk里面

----------------------org.springframework.data.domain.Chunk         版本为spring-data-commons-1.8.0.RELEASE.jar---------------

abstract class Chunk<T> implements Slice<T>, Serializable {

    private static final long serialVersionUID = 867755909294344406L;

    private final List<T> content = new ArrayList<T>();
    private final Pageable pageable;


那么,task.content最终访问的就是一个抽象类中的私有成员变量,至于理论上合不合法呢

各行研究分析

以下是解决方案

目前项目配的spring data jpa是<spring-data-jpa.version>1.6.0.RELEASE</spring-data-jpa.version>

最终找到另一份可运行的springside版本,发现里面配的版本是<spring-data-jpa.version>1.4.4.RELEASE</spring-data-jpa.version>

运行后的前面jar版本是spring-data-commons-1.6.4.RELEASE-sources.jar

可以看到

----------------PageImpl-----------

public class PageImpl<T> implements Page<T>, Serializable {

    private static final long serialVersionUID = 867755909294344406L;

    private final List<T> content = new ArrayList<T>();
    private final Pageable pageable;
    private final long total;


没使用继承了.发布后,访问成功

有兴趣的留言一起研究,求大神指点

结束,
