[Spring MVC]form:inputタグを使うサンプル

2021年5月19日

書式
form:input path=モデルの名前
1.モデルクラスの定義

public class UserModel {

private String username;

private String addr;

public UserModel(String username, String addr) {

this.username = username;

this.addr = addr;

}

public class UserModel { private String username; private String addr; public UserModel(String username, String addr) { this.username = username; this.addr = addr; } }

public class UserModel {
    private String username;
    private String addr;

    public UserModel(String username, String addr) {
        this.username = username;
        this.addr = addr;
    }

}

2.コントローラクラスの定義

@Controller

@RequestMapping("/user")

public class UserController {

@RequestMapping("/reg")

public String input(Model model) {

UserModel userModel = new UserModel("testuser", "testaddr");

model.addAttribute("userModel", userModel);

return "user/reg";

}

@Controller @RequestMapping("/user") public class UserController { @RequestMapping("/reg") public String input(Model model) { UserModel userModel = new UserModel("testuser", "testaddr"); model.addAttribute("userModel", userModel); return "user/reg"; } }

@Controller
@RequestMapping("/user")
public class UserController {
    @RequestMapping("/reg")
    public String input(Model model) {
        UserModel userModel = new UserModel("testuser", "testaddr");
        model.addAttribute("userModel", userModel);
        return "user/reg";
    }
}

3.JSP
ユーザ名: <form:input path="userModel.username" size="20″ /><br>
住所: <form:input path="userModel.addr" size="10″ maxlength="16″ /><br>
