按照注解的来源，也是分为3类
1. 内置注解 如@Override ，@Deprecated 等等
2. 第三方注解，如Hibernate, Struts等等
3. 自定义注解，如fahibernate的自定义注解
在工作中，大部分都使用的是第三方注解。那么接下来就介绍一些常用的第三方注解如:@RequestMapping、@ResponseBody、@Autowired 、@Scope、@Controller、@Service、@Repository、@Component、@RequiresPermission等等.
1 @Controller
2 @RequestMapping("/appointments")
3 public class AppointmentsController {
4
5 private AppointmentBook appointmentBook;
6
7 @Autowired
8 public AppointmentsController(AppointmentBook appointmentBook) {
9 this.appointmentBook = appointmentBook;
10 }
11
12 @RequestMapping(method = RequestMethod.GET)
13 public Map<String, Appointment> get() {
14 return appointmentBook.getAppointmentsForToday();
15 }
16
17 @RequestMapping(value="/{day}", method = RequestMethod.GET)
18 public Map<String, Appointment> getForDay(@PathVariable @DateTimeFormat(iso=ISO.DATE) Date day, Model model) {
19 return appointmentBook.getAppointmentsForDay(day);
20 }
21
22 @RequestMapping(value="/new", method = RequestMethod.GET)
23 public AppointmentForm getNewForm() {
24 return new AppointmentForm();
25 }
26
27 @RequestMapping(method = RequestMethod.POST)
28 public String add(@Valid AppointmentForm appointment, BindingResult result) {
29 if (result.hasErrors()) {
30 return "appointments/new";
31 }
32 appointmentBook.addAppointment(appointment);
33 return "redirect:/appointments";
34 }
35 }
example B)
@RequestMapping(value="/owners/{ownerId}", method=RequestMethod.GET)
public String findOwner(@PathVariable String ownerId, Model model) {
Owner owner = ownerService.findOwner(ownerId);
model.addAttribute("owner", owner);
return "displayOwner";
}
example C)
@RequestMapping("/spring-web/{symbolicName:[a-z-]+}-{version:\d\.\d\.\d}.{extension:\.[a-z]}")
public void handle(@PathVariable String version, @PathVariable String extension) {
// ... }
@Controller
@RequestMapping(value = "/pets", method = RequestMethod.POST, consumes="application/json")
public void addPet(@RequestBody Pet pet, Model model) {
// implementation omitted
}
@Controller
@RequestMapping(value = "/pets/{petId}", method = RequestMethod.GET, produces="application/json")
@ResponseBody
public Pet getPet(@PathVariable String petId, Model model) {
// implementation omitted
}
@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {
@RequestMapping(value = "/pets/{petId}", method = RequestMethod.GET, params="myParam=myValue")
public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model) {
// implementation omitted }
}
@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {
@RequestMapping(value = "/pets", method = RequestMethod.GET, headers="Referer=http://www.ifeng.com/")
public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model) {
// implementation omitted }
}
http://www.ifeng.com/”的请求；@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {
@RequestMapping("/pets/{petId}")
public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model) {
// implementation omitted
}
}
application/x-www-form-urlencoded编码的内容，提交方式GET、POST；示例代码：
@Controller
@RequestMapping("/pets")
@SessionAttributes("pet")
public class EditPetForm {
@RequestMapping(method = RequestMethod.GET)
public String setupForm(@RequestParam("petId") int petId, ModelMap model) {
Pet pet = this.clinic.loadPet(petId);
model.addAttribute("pet", pet);
return "petForm";
}
<?xml version="1.0" encoding="UTF-8" ?> <beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd" > <context:component-scan base-package=”com.eric.spring”> </beans>
@Service
public class VentorServiceImpl implements iVentorService{
}
@Repository
public class VentorDaoImpl implements iVentorDao {
}
getBean的默认名称是类名（头字母小写），如果想自定义，可以@Service(“aaaaa”)这样来指定，这种bean默认是单例的，如果想改变，可以使用@Service(“beanName”)@Scope(“prototype”)来改变。
可以使用以下方式指定初始化方法和销毁方法（方法名任意）：
@PostConstruct
public void init() {
}
@PreDestroy
public void destory() {
}
例如： @RequiresPermissions({"file:read", "write:aFile.txt"} )
void someMethod();
