Java Spring boot 2.0.1中的NoSuchMessageException

我正在尝试在我的网站中实现国际化，但不断遇到以下例外情况：

org.springframework.context.NoSuchMessageException: No message found under code 'nav_home' for locale 'en'

我的资源包位于此处：

src/main/resources/translations

这是我的配置文件：

package com.spring.henallux.FlourishBlotts.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ResourceBundleMessageSource;
import org.springframework.validation.DefaultMessageCodesResolver;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;

import java.util.Locale;

@Configuration
public class MainConfiguration implements WebMvcConfigurer {

    @Bean
    public DefaultMessageCodesResolver defaultMessageCodesResolver() {
        DefaultMessageCodesResolver defaultMessageCodesResolver = new DefaultMessageCodesResolver();
        return defaultMessageCodesResolver;
    }

    @Bean
    public ResourceBundleMessageSource resourceBundleMessageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setBasenames("translations/general", "translations/errors");
        messageSource.setUseCodeAsDefaultMessage(true);
        return messageSource;
    }

    @Bean
    public LocaleResolver localeResolver() {
        CookieLocaleResolver resolver = new CookieLocaleResolver();
        resolver.setDefaultLocale(new Locale("en"));
        resolver.setCookieName("flourish-blotts_localeCookie");
        resolver.setCookieMaxAge(-1);
        return resolver;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        LocaleChangeInterceptor interceptor = new LocaleChangeInterceptor();
        interceptor.setParamName("locale");
        registry.addInterceptor(interceptor);
    }
}

我的控制器：

package com.spring.henallux.FlourishBlotts.controller;

import com.spring.henallux.FlourishBlotts.model.LoginForm;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.MessageSource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.util.Locale;

@Controller
@RequestMapping(value="/home")
public class HomeController {

    private final MessageSource messageSource;

    @Autowired
    public HomeController(MessageSource messageSource) {
        this.messageSource = messageSource;
    }

    @RequestMapping(method = RequestMethod.GET)
    public String home (Model model, Locale locale){
        model.addAttribute("title", messageSource.getMessage("nav_home", null, locale));
        model.addAttribute("path", "home");
        model.addAttribute("loginForm", new LoginForm());
        return "integrated:home";
    }

    @RequestMapping(value="/login", method = RequestMethod.POST)
    public String login (@ModelAttribute(value="loginForm") LoginForm form){
        //TODO log user here
        return "redirect:/home";
    }
}

和我的general_en.properties文件：

nav_home=Home
nav_books=All books
nav_about=About us
nav_account=Account
nav_cart=Cart

我已经找了几个小时了，但找不到任何对我有帮助的东西 我已经在配置类中通过添加

-> classpath:
-> classpath*:
-> / before translations, with and without classpath(*)

我在使用fr语言环境时也会遇到同样的错误

当我尝试从template.jsp而不是HomeController访问任何消息时，仍然会遇到相同的错误

请帮帮我，你是我唯一的希望；）

不管怎样，我发现了我的错误

在我的配置文件中，我的ResourceBundleMessageSourcebean没有命名为messageSource（）

---

就这样——”

你把事情弄得太复杂了。删除

MessageSource

和

DefaultMessageCodesResolver

的bean，只需将

spring.messages.basename=translations/general，translations/errors

放入

应用程序.properties

。Spring Boot已经为您提供了一个

MessageSource

，只需适当地配置它（使用框架，而不是围绕框架）。
