java spring 类似_tiny4j:一个轻量级的类似Spring的实现

会点java，做点web，基本也就是spring全家桶，所以打算自己折腾一个，实现最基本最常用的一些功能。断断续续地终于完成了大部分自己想要的功能。实际项目中使用或许还不太现实，不过也提供了一个去了解框架实现的一个简单的版本，也让大家有动力有思路自己去实现一个，源码请戳github。

IOC

IOC很大程度借鉴了Spring,简单的使用

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();

//全局的容器上下文

ApplicationContextHolder holder=applicationContext.getBean("applicationContextHolder", ApplicationContextHolder.class);

System.out.println("holder get bean : "+holder.getBean("serviceBean"));

rest

实现了许多SpringMvc里高频使用的功能和一些针对restful改进的功能

@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;

}

}

看着是不是很熟悉-_- rest详细说明
