大学写的一个依赖注入框架程序
《又一个 Java Web 框架》 刚出来时没有 ioc 容器感觉不是很方便，所以想自己实现一个。之前有看过Spring源码但是发现我对Spring源码无从下手:cold_sweat:完全懵逼。之前学过怎么用Spring但是对他的底层完全不了解的我带着试一试的心态开始到处查资料，就这样我又开始造起了轮子。 如何扫描类文件 、 学习Java注解 、 Java字节码 、 动态代理 、 重新认识接口 、 一些设计模式 、 学习使用Git 、 渐渐明白了单元测试的重要性 等。随着学习的深入框架经历了数次重构，自己也对依赖注入有了自己的看法。慢慢的我发现我居然能看得明白Spring源码了。感觉Spring真心强大:open_mouth::+1: 慢慢的我感觉他并不是轻量级的:pray: 。如果他说他是轻量级，那我的就是超轻量级:smile: 。自己在造轮子的过程中学习到了很多知识，越学感觉自己越空，觉得Java是越学越多，永远都学不完。

使用说明
标识一个Bean
@Component @Component
@Target({ ElementType.TYPE, ElementType.METHOD })
public @interface Component {
/** @return bean name */
String[] value() default {};
/** @return bean's scope */
Scope scope() default Scope.SINGLETON;
String[] initMethods() default {};
String[] destroyMethods() default {};
}
复制代码
@Singleton
@Component(scope = Scope.SINGLETON)
@Target({ ElementType.TYPE, ElementType.METHOD })
public @interface Singleton {
// bean name
String[] value() default {};
String[] initMethods() default {};
String[] destroyMethods() default {};
}
复制代码
@Prototype
@Retention(RetentionPolicy.RUNTIME)
@Component(scope = Scope.PROTOTYPE)
@Target({ ElementType.TYPE, ElementType.METHOD })
public @interface Prototype {
// bean name
String[] value() default {};
String[] initMethods() default {};
String[] destroyMethods() default {};
}
复制代码
@Configuration
@Target(ElementType.TYPE)
@Component(scope = Scope.SINGLETON)
public @interface Configuration {
}
复制代码
@Service
@Component(scope = Scope.SINGLETON)
@Target({ ElementType.TYPE, ElementType.METHOD })
public @interface Service {
String[] value() default {};// bean names
}
复制代码
注入Bean
@Autowired @Resource @Inject PropertyValueResolver
@FunctionalInterface
public interface PropertyValueResolver {
default boolean supports(Field field) {
return false;
}
PropertyValue resolveProperty(Field field) throws ContextException;
}
复制代码
- 注入示例：
@Controller
@SuppressWarnings("serial")
public class LoginController implements Constant, ServletContextAware {
private String contextPath;
@Autowired
private UserService userService;
//@Inject
@Resource
private BloggerService bloggerService;
@GET("/login")
public String login(@Cookie String email, String forward, Model model) {
model.attribute(KEY_EMAIL, email);
model.attribute("forward", forward);
return "/login/index";
}
@POST("/login")
@Logger(value = "登录", //
content = "email:[${email}] " //
+ "passwd:[${passwd}] "//
+ "input code:[${randCode}] "//
+ "in session:[${randCodeInSession}] "//
+ "forward to:[${forward}] "//
+ "msg:[${redirectModel.attribute('msg')}]"//
)
public String login(HttpSession session,
@Cookie(KEY_EMAIL) String emailInCookie,
@RequestParam(required = true) String email,
@RequestParam(required = true) String passwd,
@RequestParam(required = true) String randCode,
@RequestParam(required = false) String forward,
@Session(RAND_CODE) String randCodeInSession, RedirectModel redirectModel) //
{
session.removeAttribute(RAND_CODE);
if (!randCode.equalsIgnoreCase(randCodeInSession)) {
redirectModel.attribute(KEY_MSG, "验证码错误!");
redirectModel.attribute(KEY_EMAIL, email);
redirectModel.attribute(KEY_FORWARD, forward);
return redirectLogin(forward);
}
User loginUser = userService.login(new User().setEmail(email));
if (loginUser == null) {
redirectModel.attribute(KEY_EMAIL, email);
redirectModel.attribute(KEY_FORWARD, forward);
redirectModel.attribute(KEY_MSG, email + " 账号不存在!");
return redirectLogin(forward);
}
// :yum: 略
}
@GET("/logout")
public String logout(HttpSession session) {
session.invalidate();
return "redirect:/index";
}
@Override
public void setServletContext(ServletContext servletContext) {
this.contextPath = servletContext.getContextPath();
}
}
复制代码
- 实现原理
public class AutowiredPropertyResolver implements PropertyValueResolver {
private static final Class<? extends Annotation> NAMED_CLASS = ClassUtils.loadClass("javax.inject.Named");
private static final Class<? extends Annotation> INJECT_CLASS = ClassUtils.loadClass("javax.inject.Inject");
@Override
public boolean supports(Field field) {
return field.isAnnotationPresent(Autowired.class) //
|| field.isAnnotationPresent(Resource.class) //
|| (NAMED_CLASS != null && field.isAnnotationPresent(NAMED_CLASS))//
|| (INJECT_CLASS != null && field.isAnnotationPresent(INJECT_CLASS));
}
@Override
public PropertyValue resolveProperty(Field field) {
final ApplicationContext applicationContext = ContextUtils.getApplicationContext();
final BeanNameCreator beanNameCreator = applicationContext.getEnvironment().getBeanNameCreator();
final Autowired autowired = field.getAnnotation(Autowired.class); // auto wired
String name = null;
boolean required = true;
final Class<?> propertyClass = field.getType();
if (autowired != null) {
name = autowired.value();
if (StringUtils.isEmpty(name)) {
name = byType(applicationContext, propertyClass, beanNameCreator);
}
required = autowired.required();
}
else if (field.isAnnotationPresent(Resource.class)) {
// Resource.class
final Resource resource = field.getAnnotation(Resource.class);
name = resource.name();
if (StringUtils.isEmpty(name)) { // fix resource.type() != Object.class) {
name = byType(applicationContext, propertyClass, beanNameCreator);
}
}
else if (NAMED_CLASS != null) {// @Named
final Collection<AnnotationAttributes> annotationAttributes = //
ClassUtils.getAnnotationAttributes(field, NAMED_CLASS); // @Named
if (annotationAttributes.isEmpty()) {
name = byType(applicationContext, propertyClass, beanNameCreator);
}
else {
name = annotationAttributes.iterator().next().getString(Constant.VALUE); // name attr
}
}
else {// @Inject
name = byType(applicationContext, propertyClass, beanNameCreator);
}
return new PropertyValue(new BeanReference(name, required, propertyClass), field);
}

使用 @Props 注入Properties或Bean
- 构造器
@Autowired
public PropsBean(@Props(prefix = "site.") Bean bean) {
//---------
}
@Autowired
public PropsBean(@Props(prefix = "site.") Properties properties) {
//-------
}
@Autowired
public PropsBean(@Props(prefix = "site.") Map properties) {
//-------
}
复制代码
- Field
@Props(prefix = "site.")
Bean bean;
@Props(prefix = "site.")
Map properties;
@Props(prefix = "site.")
Properties properties
复制代码
- 实现原理
@Order(Ordered.HIGHEST_PRECEDENCE - 2)
public class PropsPropertyResolver implements PropertyValueResolver {
@Override
public boolean supports(Field field) {
return field.isAnnotationPresent(Props.class);
}
}
复制代码
使用 @Value 支持EL表达式
@Props
#{key}
${1+1}
@Configuration
public class WebMvc implements WebMvcConfiguration {
private final String serverPath;
@Autowired
public WebMvc(@Value("#{site.serverPath}") String serverPath) {
this.serverPath = serverPath;
}
@Override
public void configureResourceMappings(ResourceMappingRegistry registry) {

@Configuration 注解
