我正在 Spring 制作网络应用程序。我制作了简单的表单来创建带有密码的用户(对于 Spring 安全性)，但我无法将这些值传递给 MySql。我有另一个工作表格，所以连接没有问题。控制台无异常。

这是代码。

.jsp 文件

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    <%@ taglib prefix="sf" uri="http://www.springframework.org/tags/form"%>



<center><h2>Dodaj Użytkownika</h2>
<sf:form action="${pageContext.request.contextPath}/usercreate" method="post"
    modelAttribute="users">

    <table>
        <tr>
            <td>Nazwa użytkownika</td>
            <td><sf:input path="${username}" name="username"
                    type="text" /><br />
            <div class="error">
                    <sf:errors path="username"></sf:errors>
                </div></td>
        </tr>
        <tr>
            <td class="label">Hasło:</td>
            <td><sf:input path="${password}"
                    name="password" type="password" />
                <div class="error">
                    <sf:errors path="password"></sf:errors>
                </div></td>
        </tr>
        <tr>
            <td class="label"></td>
            <td><input class="control"  type="submit" value="Dodaj Użytkownika"/></td>
        </tr>
    </table>

</sf:form>
</center>

Controller 

@Controller
public class UserController {

private Servicu servicu;

@Autowired
public void setServicu(Servicu servicu) {
    this.servicu = servicu;
}
@Autowired
PasswordEncoder PasswordEncoder;

@RequestMapping("/users")
public String newUser(Model model){
    model.addAttribute("users", new Users());

    return "users";

}

@RequestMapping(value="/usercreate", method= RequestMethod.POST)
public String userCreated(@ModelAttribute("users") Users users,Model model){


//      if(result.hasErrors()){
//          return "login";
//      }
    model.addAttribute("users", users);

    users.setEnabled(true);
    users.setAuthority("ROLE_USER");

        servicu.create(users);
        servicu.createAuth(users);

    return "home";
}

DAO

@Component("userDAO")
public class UserDAO {

private NamedParameterJdbcTemplate jdbc;

@Autowired
private PasswordEncoder PasswordEncoder;

@Autowired
public void setPasswordEncoder(PasswordEncoder passwordEncoder) {
    PasswordEncoder = passwordEncoder;
}

@Autowired
public void setDataSource(DataSource jdbc) {
    this.jdbc = new NamedParameterJdbcTemplate(jdbc);
}


public boolean createUser(Users users) {

    MapSqlParameterSource params = new MapSqlParameterSource();

    params.addValue("username", users.getUsername());
    params.addValue("password", PasswordEncoder.encode(users.getPassword()));
    params.addValue("enabled", users.isEnabled());

    return jdbc.update("insert into users (username, password,enabled) values (:username, :password,:enabled)",
            params) == 1;

}

public boolean createAuth(Users users) {

    MapSqlParameterSource params = new MapSqlParameterSource();

    params.addValue("username", users.getUsername());

    params.addValue("authority", users.getAuthority());

    return jdbc.update("insert into authorities (username, authority) values (:username, :authority)", params) == 1;
}

临时 spring sec 允许访问所有 jsps，验证标记被删除。

编辑:

我的服务文件

@Service("servicu")
public class Servicu {

    @Autowired
    private OffersDAO offersDAO;
    @Autowired
    private UserDAO userDAO;

    @Autowired
    public void setOffersDAO(OffersDAO offersDAO) {
        this.offersDAO = offersDAO;
    }

    @Autowired
    public void setUserDAO(UserDAO userDAO) {
        this.userDAO = userDAO;
    }

    public List<Hospitals> getCurrent(){
        return offersDAO.getHosps();
    }



    public void create(OrdersPatient ordersPatient) {
        offersDAO.createPatient(ordersPatient);


    }

    public void create(Orders orders) {
        offersDAO.createOrder(orders);

    }

    public void create(Users users) {
        userDAO.createUser(users);

    }

    public void createAuth(Users users) {
        userDAO.createAuth(users);

    }

和安全上下文 xml

</security:http>
<bean id="PasswordEncoder"
    class="org.springframework.security.crypto.password.StandardPasswordEncoder">
</bean>
<security:global-method-security secured-annotations="enabled"></security:global-method-security>

最佳答案

这个问题的解决很简单。我发现我没有放

<security:intercept-url pattern="/usercreate" access="permitAll"/>

在我的安全上下文中。

这映射到我的方法。现在一切正常。
