Java 为什么第一个属性可以解析，但不能解析同一对象的第二个属性

目前在一个web应用程序项目中，我以jsp的形式上传了1个值和1个多文件。 我已经尝试过我的第一个chartType可以用作属性，但其他两个不能

使用：JavaSpring、mnv、jsp运行

JSP

错误 '属性[ChartTitle]在类型[com.si.dashboard.model.Chart]上不可读 javax.el.PropertyNotFoundException:类型[com.si.dashboard.model.Chart]上的属性[ChartTitle]不可读'

chart.java

}/P>< P>好的家伙，所以我想办法，JSP实际上称为图表，并错过了一个大写字母从我的吸气剂GETCARTTITTLE到GETCARTITTITLE，做这个工作，谢谢大家。< / P>英文单词标题没有拼写双T在中间。我不知道这是否与您的错误有关。不应该是，英文单词title在jsp中，是javascript的一种形式，我的title变量来自java servletin jsp，您的“title”拼写正确。为了证明您的观点，我已经将所有title更改为title，现在错误是boldProperty[chartTitle]在类型上不可读[com.si.dashboard.model.Chart]javax.el.PropertyNotFoundException:Property[chartTitle]在[com.si.dashboard.model.Chart]类型上不可读，所以它是相同的，如果我更改变量名也没关系
