使用 spring boot 从 mysql table table 中获取 id 并与 url 连接

Question

我已将下面的 ID 硬编码为 1，但我需要从 EMPLOYEE 数据库的雇员详细信息 table 中获取 ID

int id=1; //This id needs to come from table from column id


public void addViewControllers(ViewControllerRegistry registry) {   
    registry.addViewController("/home").setViewName("home");
    registry.addRedirectViewController("/", "/applyleave/"+ id);
}

@Autowired
public DataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName("com.mysql.jdbc.Driver");
    dataSource.setUrl("jdbc:mysql://localhost:3306/EMPLOYEE");
    dataSource.setUsername("root");
    dataSource.setPassword("password");
    return dataSource;
}

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth
    .jdbcAuthentication().dataSource(dataSource()).usersByUsernameQuery("select user_id, password, loginstatus from employeedetails where user_id=? ").authoritiesByUsernameQuery("select user_id, role from employeedetails where user_id=? ");
}

如何使用 spring 引导 java 配置实现此目的？

Answer 1

无论我从你的问题中了解到什么，我都有一个解决方案在 EmployeeDAO
中写一个你的员工查询这里的 Employee 是所有 getter setter 方法的实体 class

public Employee getByUserId(Integer userId) {

//return your query for userId here

}

然后在您的用户 class 中调用此 class，您必须在其中使用员工 ID

@Autowired
EmployeeDAO employeeDAO;

public void addViewControllers(ViewControllerRegistry registry) {

  Employee employee = employeeDAO.getByUserId(//pass your user id here)
   id = employee.getId();

   registry.addViewController("/home").setViewName("home");
   registry.addRedirectViewController("/", "/applyleave/"+ id);
}

这样就可以在这里使用employeeId了

这个方法是控制器解决的问题。

@RequestMapping(value = "/", method = RequestMethod.GET)
public String getid() {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        String userid = auth.getName();
        int id=employeeDaoImpl.getIdByUserId(userid);
        return "redirect:/applyleave/"+id;
    }

谢谢大家！！！
