我正在尝试在 Tomcat 服务器上实现一个注册页面，但是没有创建支持 bean，当我单击提交按钮时出现以下错误。
Caused by: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'registerBean' resolved to null at org.apache.el.parser.AstValue.getTarget(AstValue.java:98) at org.apache.el.parser.AstValue.getType(AstValue.java:82) at org.apache.el.ValueExpressionImpl.getType(ValueExpressionImpl.java:172) at com.sun.faces.facelets.el.TagValueExpression.getType(TagValueExpression.java:98)
这是RegisterBean.java
package com.please.beans;
import java.io.Serializable;
import javax.enterprise.context.SessionScoped;
import javax.inject.Named;
@Named
@SessionScoped
public class RegisterBean implements Serializable{
private String emailAddress="3234234";
private String userName;
private String password;
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public void doLogin(){
System.out.println("Test sucessful");
}
}
