tiny4j:一個輕量級的類似Spring的實現

twogoods發表於2016-12-04
Spring

會點java，做點web，基本也就是spring全家桶，所以打算自己折騰一個，實現最基本最常用的一些功能。斷斷續續地終於完成了大部分自己想要的功能。實際專案中使用或許還不太現實，不過也提供了一個去了解框架實現的一個簡單的版本，也讓大家有動力有思路自己去實現一個，原始碼請戳github。

IOC

IOC很大程度借鑑了Spring,簡單的使用

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("test.xml");
ServiceBean serviceBean=(ServiceBean)applicationContext.getBean("testService");
System.out.println(serviceBean);
serviceBean.service();

ServiceBean serviceBean2=(ServiceBean)applicationContext.getBean("serviceBean");
System.out.println(serviceBean2);
serviceBean2.service();

//全域性的容器上下文
ApplicationContextHolder holder=applicationContext.getBean("applicationContextHolder", ApplicationContextHolder.class);
System.out.println("holder get bean : "+holder.getBean("serviceBean"));

rest

實現了許多SpringMvc裡高頻使用的功能和一些針對restful改進的功能

@Api("/base")
public class TestController extends BaseController {

    @Value("${user.name:test}")
    private String name;

    @Inject
    private UserService userService;

    @RequestMapping
    public String index() {
        userService.query();
        return name;
    }

    @RequestMapping(mapUrl = "/test/{id}", method = HttpMethod.GET)
    @CROS(origins = "www.baidu.com", methods = {HttpMethod.GET}, maxAge = "3600")
    public String patgTest(@PathVariable("id") String id) {
        return id;
    }

    @RequestMapping(mapUrl = "/test", method = HttpMethod.GET)
    @InterceptorSelect(include = {"aInterceptor"}, exclude = {"bInterceptor"})
    public String interceptorTest() {
        return "haha";
    }


    @RequestMapping(mapUrl = "/index")
    @CROS
    public String paramTest(@RequestParam("id") long id, @RequestParam("name") String name) {
        return name + "---" + id;
    }

    @RequestMapping(mapUrl = "/user/{id}", method = HttpMethod.PUT)
    @CROS
    public User insert(@PathVariable("id") long id, @RequestBody User user) {
        return user;
    }
}

看著是不是很熟悉-_- rest詳細說明
