Spring mvc 映射问题

Question

我正在为一个项目使用 spring mvc hibernate。 现在我被困在我的地图上。

正常的网址是： localhost:8080/Carre2/......

有些页面有一些参数，比如 localhost:8080/Carre2/addproduct/edit/1

当我想去另一个页面时，他要求： localhost:8080/Carre2/addproduct/edit/home

我不知道如何解决这个映射问题。 有人可以帮忙吗？

一些代码：

public class AddproductController {

private ProductService productService;

@Autowired(required = true)
@Qualifier(value = "productService")
public void setProductService(ProductService ps) {
    this.productService = ps;
}

@RequestMapping(value = "/addproduct", method = RequestMethod.GET)
public String listProduct(Model model) {
    model.addAttribute("product", new Product());
    model.addAttribute("listProduct", this.productService.listProduct());
    return "addproduct";
}

//For add and update person both
@RequestMapping(value = "/addproduct/add", method = RequestMethod.POST)
public String addProduct(@ModelAttribute("product") Product p) {

    if (p.getId() == 0) {
        //new person, add it
        this.productService.addProduct(p);
    } else {
        //existing person, call update
        this.productService.updateProduct(p);
    }

    return "redirect:/addproduct";

}

@RequestMapping("addproduct/update/{id}")
public String updateProduct(@PathVariable("id") int id, Model model) {
    model.addAttribute("product", this.productService.getProductById(id));
    model.addAttribute("listProduct", this.productService.listProduct());
    return "productlist";
}

@RequestMapping("addproduct/edit/{id}")
public String editProduct(@PathVariable("id") int id, Model model) {
    model.addAttribute("product", this.productService.getProductById(id));
    model.addAttribute("listProduct", this.productService.listProduct());
    return "addproduct";
}

这里是我的 servlet-context.xml

这是我想要访问该 url 的方式。 c:url value='addproduct/edit/${product.id}'

Answer 1

我建议使用 c:url 来修复它：

c:url value="${pageContext.request.contextPath}/addproduct/edit/${product.id}"

基本上尝试为每个 c:url 取 ${pageContext.request.contextPath}

它将转换为“localhost:8080/Carre2”

Answer 2

你只需要按如下方式访问它，

c:url value='/addproduct/edit/${product.id}'

这将使url 从您的上下文路径开始。

或者更好的方法是全局存储上下文路径并在每个 url 中使用它。可以参考上下文路径如下，

c:url value="${pageContext.request.contextPath}/addproduct/edit/${product.id}"
