Details of ② request method

Query Request:

/**
 * Company ID get company Information
  CompanyID Company ID
 *
/@GetMapping ("/getcompanyinfo/{companyid}")
Public Resultinfo Getconame (@PathVariable ("CompanyID") Integer CompanyID) {
    date lastday = new Date (new Date (). GetTime () -24*60*60*1000);
    map<string,object> map = Maps.newhashmap ();
    Company Company = Companyservice.selectbyprimarykey (CompanyID);
    Map.put ("Name", Company.getcompanyname ());//Enterprise name
    map.put ("icon", Company.getthumbnails ());//thumbnail
    map.put ("Staffnum", Companyservice.getstaffnum (CompanyID));//Get the number of users
    map.put ("Workshopnum", Companyservice.deptcount (CompanyID)); /Get Department number
    map.put ("Lastdaynum", Companyservice.singupnum (Companyid,lastday));//number of users yesterday
    return  Success (map);
}

New request:

/**
 * Add roles
  role
 @return
*
/@PostMapping ("/addrole")
public Resultinfo addrole (role role) {

    int i = rolegroupservice.addrole (role);

    Return i>0?success ("Add Role succeeded"): Success ("Add role Failed");
}

Delete request:

Delete Employee
@DeleteMapping ("/delete/{id}") Public
Resultinfo Deletebyprimarykey (@PathVariable ("id") Long ID) {
    return (Staffservice.deletebyprimarykey (ID) > 0)? success ("Delete succeeded"): Success ("delete failed");
}

To modify a request:

@RequestMapping (value= "/{id}", method=requestmethod.put) public
String Putuser (@PathVariable Long ID, @ Modelattribute User user) {
    //processing "/users/{id}" put request to update user information
    user U = users.get (id);
    U.setname (User.getname ());
    U.setage (User.getage ());
    Users.put (ID, u);
    Return "Success";
}

Of course

@RequestMapping (value= "/{id}", Method=requestmethod.put)

can be used

@PutMapping ("/{id}")

Alternative, the other way of requesting the same. @ParaVariable annotations have passed the parameters in {} to the variable of the annotation declaration, which is easy to use and at a glance.
