spring boot——参数传递——URL后面接参数：示例：?username=1221&age=12——通过Bean对象来获取前端页面参数

创建Bean对象：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

package com.awaimai.web;   public class Student {     private String firstName;     private String lastName;       public void setFirstName(String firstName)     {         this.firstName = firstName;     }       public String getFirstName()     {         return firstName;     }       public void setLastName(String lastName)     {         this.lastName = lastName;     }       public String getLastName()     {         return lastName;     }   }

控制器：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

package com.awaimai.web;   import org.springframework.web.bind.annotation.*;   @RestController public class kzq {       @RequestMapping(value = "/test2")     public String test2(Student student)     {         String a = student.getFirstName();         String b = student.getLastName();         return a+b;     }   }

web访问：

    @RequestMapping(value = "/test291")
