    在这个ApplicationContext.xml文件中出现 如下报错

    Element : property

    Bean definitions can have zero or more properties. Property elements correspond to JavaBean setter 

     methods exposed by the bean classes. Spring supports primitives, references to other beans in the same or 

     related factories, lists, maps and properties.

    Content Model : (description?, (meta | bean | ref | idref | value | null | array | list | set | map | props | 

     namespace:uri="##other")?)

    或者

    Multiple annotations found at this line:

    - No constructor with 0 arguments defined in class 

    'cn.lonecloud.bean.step08iocfieldbyProperty.UserBean'

    请在自己导入的实体bean中检查是否没有加无参数的构造函数

    package cn.lonecloud.bean.step08iocfieldbyProperty;
    
    public class UserBean {
    
        private String userName;
        
        private int age;
        
        private String address;
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
        public String getAddress() {
            return address;
        }
    
        public void setAddress(String address) {
            this.address = address;
        }
        
        @Override
        public String toString() {
            return "UserBean [userName=" + userName + ", age=" + age + ", address="
                    + address + "]";
        }
        //如果在这个实体bean中设置了这个带构造函数的构造方法则需要在这里加一个无参数的构造函数
        public UserBean(){
            
        }
        public UserBean(String userName, int age, String address) {
            super();
            this.userName = userName;
            this.age = age;
            this.address = address;
        }
    }
