【问题描述】
数据新增时,需要 trim,写了个 通用的 trim 类,
参考 QueryGenerator.java 写的,结果报错:
java.lang.NoSuchMethodException: Property 'xxx' has no setter method in class 'class org.jeecg.modules.xxx.entity.xxx'

【解决方案】
添加
static {
PropertyUtils.addBeanIntrospector(new FluentPropertyBeanIntrospector());
}
【注意】
在 QueryGenerator.java 里也必须添加
查看 PropertyUtils 源码:
这里用了单例模式: PropertyUtilsBean.getInstance()
