Nutz简单项目创建

Nutzwk3.X

Web.xml配置
在web.xml中配置nutz的过滤器来进行配置项目启动项目

<filter> <filter-name>nutz</filter-name> <filter-class>org.nutz.mvc.NutFilter</filter-class> <init-param> <param-name>modules</param-name> <param-value>cn.main.Module</param-value> 启动经过的主类 Module为类名 </init-param> </filter> <filter-mapping> <filter-name>nutz</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping>

入口类：必须要有的入口类

入口类 @Modules(scanPackage = true, packages = "cn.modules") @Ok("json:full") @Fail("http:500") @IocBy(type = ComboIocProvider.class, args = {"*json","ioc/", "*anno", "cn.modules"}) @Localization(value = "locales/", defaultLocalizationKey = "zh_CN") @Encoding(input = "UTF-8", output = "UTF-8") public class Module { }

Controller访问层

@IocBean public class HelloController { @Inject private BookService bookService; @At("/hello") @Ok("jsp:/index.jsp") public String hello(){ return "hello nutz"; } @At("/loginPage") @Ok("jsp:/templates/login.jsp") public String loginPage(){ return "hello nutz"; } @At("/doLogin") @Ok("jsp:/templates/index.jsp") public String login(String username,String password){ Book book = new Book(); book.setName(username); bookService.dao().insert(book); return "success"; } }

Service
Service层继承nutz提供的service 但必须注入dao配置

Service 可以继承EntityService 但必须要有注入dao的配置

@IocBean(args = {"refer:dao"}) public class BookService extends EntityService<Book> { public BookService(Dao dao) { super(dao); } }

IOC dao数据源及数据库配置（访问数据库必备）

Ioc/dao.json配置

var ioc = { dataSource : { type : "com.alibaba.druid.pool.DruidDataSource", events : { create : "init", depose : 'close' }, fields : { url : "jdbc:mysql://127.0.0.1:3306/nutzwk",//数据库的地址 username : "root", password : "root", testWhileIdle : true, // 非常重要,预防mysql的8小时timeout问题 validationQuery : "select 1" , // Oracle的话需要改成 select 1 from dual maxActive : 100 } }, dao : { type : "org.nutz.dao.impl.NutDao", args : [{refer:"dataSource"}] } };
