... 40 more网上大致上找了下，都说asm.jar和asm-2.2.3.jar有冲突，但是我jar包里面这两个都没有，用的是asm-3.1.jarssh

Answer 1

学了两年的JAVA没派上用场，想跳槽重新再来，求大神指点！

Answer 2

Error setting property values

Answer 3

如果不是asm-3.1.jar 的问题，可能就是缺少某个jar包了！

Answer 4

asm-3.1.jar 这个包我去掉试过了，也是一样的情况。

Answer 5

DPAction对应的配置文件看下，看下属性值得getXXX和你配置文件的是否一样

Answer 6

.beans.NotWritablePropertyException: Invalid property 'foodDao' of bean class [com.tudou.action.DPAction]: Bean property 'foodDao' is not writable 
set方法名,检查下,建议使用注解,类路径自动扫描....

Answer 7

Invalid property 'foodDao' of bean class [com.tudou.action.DPAction]: Bean property 'foodDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
DPAction中对应的属性foodDao的setter和getter方法保持一致
