5.org.hibernate.exception.SQLGrammarException: could not initialize a collection
检查以下内容是否出错:
inverse="true" 是否在一对多或多对多中设定一方去维持两者之间的关系; 或者用注解的方式配置则是:
//One
@OneToMany(fetch = FetchType.LAZY, mappedBy = "movie_id", cascade = {
CascadeType.PERSIST, CascadeType.REFRESH }, targetEntity = Users.class)
@Column(name = "movie_id", nullable = false, updatable = false)
//Many
@ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "movie", insertable = true, updatable = true, nullable = false)
cascade="delete" 级联删除
<key>
<column name="movie_id" /> 此处应填上另一方表的字段名!
</key>
6. freemarker 中在一循环列表中,判断某条记录是否包含指定的字符串。
<#list al as l> <#if l.info?indexof("xxx") != -1> ${l.name!} </#if> </#list>
本以为很简单的一个逻辑判断语句,但是在实际操作中,指定的字符串“xxx”,不是已知的,而是一个变量,这里我就用str表示
那么l.info?indexof(str) != -1 这条语句将会报args参数错误! 原因在于传递进来的str类型不是string
在此i.info?indexof("str") != -1 不会报错,但是很明显,这样的话str变量将不会被解析。
为了达到逻辑语句成立,我只能在l.info那做文章---将每个元素用 , 隔开,然后将indexof()判断的字符串改变,得到indexof("," + str + ",");
此时有人会提出,我可以直接写成这样就行了啊----indexof("\"" + str +"\""); 答案是否定的
