目前我的代码可以修改客户名字、客户年龄，但是无法修改客户订单。
客户类
public class Customer {
private Integer cid;
private String cname;
private Integer age;
private Set<Orders> orders = new HashSet<Orders>();
getter&setter
public String toString() {
return "Customer [cid=" + cid + ", cname=" + cname + ", age=" + age + ", orders=" + orders
+ "]";
}
}
订单类
public class Orders {
private Integer oid;
private String addr;
private Customer customer;
getter&setter
public String toString() {
return "Orders [oid=" + oid + ", addr=" + addr + "]";
}
}
action
public class CustomerAction extends ActionSupport implements ModelDriven<Customer> {
private Customer customer = new Customer();
public Customer getModel() {
return customer;
}
private CustomerService customerService;
public void setCustomerService(CustomerService customerService) {
this.customerService = customerService;
}
public String upd() throws Exception{
customerService.upd(customer);
return SUCCESS;
}
}
jsp

参考http://bbs.csdn.net/topics/390648778?page=1
添加了CustomerAction-conversion.properties(不清楚写对了没)
KeyProperty_orders = oid
Element_orders = cn.xx.vo.Orders
CreateIfNull_orders =true
运行报错
WARN OgnlValueStack:64 - Error setting expression 'orders.makeNew[0].addrcidoid' with value '[Ljava.lang.String;@1d6d441'
