target is null for setProperty(null, "name", [Ljava.lang.String;@ffc6ae)

如题 target is null for setProperty(null, "name", [Ljava.lang.String;@ffc6ae)

严重: Could not create and/or set value back on to object

Method "setProductType" failed for object net.epsshop.action.admin.ProductTypeAction@163bad4 - Class: ognl.OgnlRuntime

File: OgnlRuntime.java

Method: callAppropriateMethod

Line: 1265 - ognl/OgnlRuntime.java:1265:-1

ognl.MethodFailedException: Method "setProductType" failed for object net.epsshop.action.admin.ProductTypeAction@163bad4 [java.lang.NoSuchMethodException: net.epsshop.action.admin.ProductTypeAction.setProductType($Proxy39)]

警告: Error setting expression 'productType.name' with value '[Ljava.lang.String;@ffc6ae'

get和set方法都有

这个破问题困扰我一天，以前遇到过，又忘了。。。（哎，人老了记性不太好了）

解决：

将

private ProductType productType ;

改成

private ProductType productType = new ProductType();
//初始化（其实我到现在都郁闷，以前都是没有初始化怎么都没出错，有高手路过的，知道原因的请告诉在下，谢谢了！）
