概述

在Spring MVC中選擇語言區(qū)域，可以使用語言解析器Bean，它包括幾個(gè)實(shí)現(xiàn)，如下

AcceptHeaderLocaleResolver

SessionLocaleResolver

CookieLocaleResolver

其中上篇博文 已經(jīng)已經(jīng)講解了 Spring MVC-08循序漸進(jìn)之國(guó)際化(AcceptHeaderLocaleResolver)

接下來我們來通過SessionLocaleResolver來實(shí)現(xiàn)國(guó)際化

工程結(jié)構(gòu)

實(shí)體類 標(biāo)注了JSR303校驗(yàn)

package com.artisan.domain; import java.io.Serializable;import javax.validation.constraints.Size;import org.hibernate.validator.constraints.NotBlank;public class Product implements Serializable {private static final long serialVersionUID = 78L;@NotBlank@Size(min=1, max=10)private String name;private String description;private Float price;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}public Float getPrice() {return price;}public void setPrice(Float price) {this.price = price;} }

控制層

package com.artisan.controller;import javax.validation.Valid;import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.validation.BindingResult; import org.springframework.validation.FieldError; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping;import com.artisan.domain.Product;@Controller @RequestMapping("/product") public class ProductController {private static final Log logger = LogFactory.getLog(ProductController.class);@RequestMapping(value="/product_input")public String inputProduct(Model model) {model.addAttribute("product", new Product());return "ProductForm";}@RequestMapping(value="/product_save")public String saveProduct(@Valid @ModelAttribute Product product, BindingResult bindingResult,Model model) {// 校驗(yàn)if (bindingResult.hasErrors()) {FieldError fieldError = bindingResult.getFieldError();logger.info("Code:" + fieldError.getCode() + " ,field:" + fieldError.getField());return "ProductForm";}// save product heremodel.addAttribute("product", product);return "ProductDetails";}}
