jsp 運行時報錯Cannot find a method to write property [firstName] of type [java.lang.String] in a bean of type [main.Employee]

原因: 代碼沒有安裝bean的格式寫 setFirstName寫成了setFristName

錯誤代碼

public void setFristName(String firstName) {
        this.firstName = firstName;
    }

修改代碼后通過

public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
