新手小白，如何新建一个springboot的web项目？

news2025/1/16 7:45:42

第一步：打开软件，点击file，点击new 然后选择module，在右侧选择springboot

第二步：选择配置和JDK以及java版本

①选择maven类型

②选择JDK1.8版本

③选择java8版本

④选择jar包类型

如果不知道或者找不到配置8版本，可以看下面的链接：

第三步：选择加载配置，一般我们默认选择web项目就行

之后我们稍等一会，让他建立项目！~

第四步：测试

新版本会自动创建controller，我的版本是2024.1月的新版本，因此会创建好示例，如果比较老的版本是不会有的，也可以复制我下面的代码文件：

        User user = new User();
        user.setName("theonefx");
        user.setAge(666);
        return user;
    }

    // http://127.0.0.1:8080/save_user?name=newName&age=11
    @RequestMapping("/save_user")
    @ResponseBody
    public String saveUser(User u) {
        return "user will save: name=" + u.getName() + ", age=" + u.getAge();
    }

    // http://127.0.0.1:8080/html
    @RequestMapping("/html")
    public String html() {
        return "index.html";
    }

    @ModelAttribute
    public void parseUser(@RequestParam(name = "name", defaultValue = "unknown user") String name
            , @RequestParam(name = "age", defaultValue = "12") Integer age, User user) {
        user.setName("zhangsan");
        user.setAge(18);
    }
}
