Bootstrap

Spring4.2.6+SpringMVC+Mybatis+mysql+Gradle使用IDEA搭建

前段时间刚换成IDEA+Gradle开发  自己稍微的记录一下咯

先创建项目

选择自己本地安装的gradle   和maven差不多，算是个本地库吧。然后next输入你的项目名进行创建 最后会生成一个空的项目出来

╮(￣▽￣")╭ 虽然IDEA能够自己生成好多完整的配置 but 本人比较菜 不怎么会弄 还是自己手动写比较方便点。。。

下一步 先不管gradle配置文件  先去创建完整的项目结构，这些文件夹我选择自己手动创建，这时候就只剩下webapp的配置文件了 在Project structrue配置里面

然后把这块的配置改成之前创建的webapp目录 点击完成 一个正常的项目就创建完毕 ╮(￣▽￣")╭虽然看着麻烦 但是能够有效的避免掉其他错误

在IDEA里面 包是不会自动的下载 需要我们手动的build下载 如果找不见build在哪里 请看软件最右侧 应该是有Gradle的选项 点开后有刷新的按钮 正常人都能看到╮(￣▽￣")╭


下面先是build.gradle的配置文件

apply plugin: 'java'
//IntelliJ IDEA 插件
apply plugin: 'idea'
//war包插件
apply plugin: 'war'
//jdk版本
sourceCompatibility = 1.8
version = '1.0'
//下载地址  同样是在maven库里 选择gradle的标签进行复制
repositories {
    maven {
        url "http://www.mvnrepository.com/"
    }
    mavenCentral()
}
//下面的文件可能有些是不需要的  是之前自己项目的配置 但是只多不会少 就直接粘了过来

一共三个格式的后缀名 .do返回视图 .json返回json格式的数据 .xml返回xml格式的数据  视图用到了freemarker 不需要的可以去掉 用下面注释的标签

在Controller返回视图的时候 需要用ModelAndView进行返回 格式类似下面

    @RequestMapping(value = "test")
    public ModelAndView xxx(HttpServletRequest request){
        ModelAndView mav = new ModelAndView();
        Map<Object, Object> map = new HashMap<Object,Object>();
        List list = new ArrayList<Object>();
        map.put("id" ,request.getParameter("id"));
        map.put("name","暖心大人");
        list.add("暖心大人");
        mav.addObject(list);

        mav.setViewName("/WEB-INF/view/user1.html");
        System.out.print(list);
        return mav;
    }
这时候 三种后缀名都可以返回对应的视图和数据

Mybatis的mapper也没什么特殊的地方了 自行解决掉。。。。。如果没有什么问题出现 项目的大体框架就已经配置完成了

悦读

道可道，非常道；名可名，非常名。 无名，天地之始，有名，万物之母。 故常无欲，以观其妙，常有欲，以观其徼。 此两者，同出而异名，同谓之玄，玄之又玄，众妙之门。
