使用web语言编译时出现错误?该怎么办？求大佬！

Question

用struts框架在action.java中出现错误：The type LoginAction must implement the inherited abstract method SessionAware.setSession(Map)和Name clash: The method setSession(Map<String,Object>) of type LoginAction has the same erasure as setSession(Map) of type SessionAware but does not override it

Answer 1

SessionAware这个是在struts2中action需要取Session用到的接口。如果你的LoginAction实现这个接口，就需要重写这个接口的方法
在LoginAction加入
//请求访问 session
private Map<String, Object> session;
@Override
public void setSession(Map<String, Object> session) {
this.session = session;
}
