验证消息未从application.properties文件中读取

标签： spring spring-mvc spring-boot

我有一个带有验证的登录页面。但是问题是，即使我输入了 ReloadableResourceBundleMessageSource ，只要用户输入错误的数据，它都应该显示错误消息，而不是抛出错误在代码下找不到消息... 。在我的 RootAppConfig.class 中。

注意：：写在application.properties中的属性消息，放置在 src / main / resources / application.properties 中，我的jsp文件放置在 webapp / web中-inf / pages / insert.jsp

RootAppConfig.clas ------------------ 

@SpringBootApplication
@Import(value= {PersistenceConfig.class,AopConfig.class,ServiceConfig.class})
public class RootAppConfig {

    public static void main(String[] args) {
        SpringApplication.run(RootAppConfig.class, args);
    }

    @Bean
    public MessageSource createSouce() {
        ReloadableResourceBundleMessageSource source= new ReloadableResourceBundleMessageSource();
        source.setBasename("classpath:application");//I have tried only application too
        return source;
    }
}


ServletInitializer.class -------------------------- 

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MvcAppConfig.class,RootAppConfig.class);
    }

}

application.properties
----------------------------- 

#in-built container
server.port= 8081

#datasource
spring.datasource.jndi-name= java:/comp/env/DsJndi

#view resolver
spring.mvc.view.prefix= /WEB-INF/pages/
spring.mvc.view.suffix= .jsp

#form vallidator
name.required= Employee Name Cannot Be Empty
mobile.required= Mobile Number Is Not Valid
address.required= Address Cannot Be Empty
company.required= Company Name Cannot Be Empty
salary.required= Salary Field Cannot Be Empty

EmployeeValidator.class
---------------------------- 

@Component
public class EmployeeVallidator implements Validator {

    @Override
    public boolean supports(Class<?> clazz) {
        // TODO Auto-generated method stub
        return clazz.isAssignableFrom(EmployeeCommand.class);
    }

    @Override
    public void validate(Object command, Errors errors) {
        EmployeeCommand cmd= null;

        cmd= (EmployeeCommand) command;

        if(cmd.getName().equals("")||cmd.getName().length()==0) {
            errors.rejectValue("name", "name.required");
        }
        if(Long.toString(cmd.getMobile()).length()<10||Long.toString(cmd.getMobile()).equals("")) {
            errors.rejectValue("mobile", "mobile.required");
        }
        if(cmd.getAddress().equals("")||cmd.getAddress().length()==0) {
            errors.rejectValue("address", "address.required");
        }
        if(cmd.getCompany().equals("")||cmd.getCompany().length()==0) {
            errors.rejectValue("company", "company.required");
        }
        if(cmd.getSalary()<=0) {
            errors.rejectValue("salary", "salary.required");
        }

    }

控制器
----------------- 

public class AppController {

    @Autowired
    private EmployeeVallidator vallidator;
    @Autowired
    private EmployeeService service;

    @RequestMapping(value="/home")
    public String showHome() {
        return "homePage";
    }

    @RequestMapping(value="/success")
    public String returnSuccess() {
        return "success";
    }

    @RequestMapping(value="/insert",method= RequestMethod.GET)
    public String showInsertPage(@ModelAttribute("empCmd")EmployeeCommand cmd) {
        return "insert-record";
    }

    @RequestMapping(value="/insert",method=RequestMethod.POST)
    public String processRegistration(@ModelAttribute("empCmd")@Valid EmployeeCommand cmd,BindingResult errors,HttpSession session) {
        EmployeeDto dto= null;
        String result= null;
        if(vallidator.supports(EmployeeCommand.class)) {
            vallidator.validate(cmd, errors);

            if(errors.hasErrors()) {
                return "insert-record";
            }
        }

        dto= new EmployeeDto();
        BeanUtils.copyProperties(cmd, dto);
        try {
            result= service.pushEmployee(dto);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        session.setAttribute("message", result);
        return "redirect:/success";
    }
