来源：互联网发布：电脑编程入门视频教程编辑：程序博客网时间：2024/04/29 23:52

在项目常用jesery作为rest开发的框架,jesery简单快捷,易于扩展方便使用,在这里我们学习一下mule和jesery的整合使用.

1.简单的绑定一个资源请求路径:

Xml代码

1. <service name="helloWorldResource">

2. <inbound>

3. <inbound-endpoint address="http://localhost:63081/" exchange-pattern="request-response"/>

4. </inbound>

5. <jersey:resources>

6. <component class="org.mule.module.jersey.HelloWorldResource"/>

7. </jersey:resources>

8. </service>

Java代码

1. import javax.ws.rs.DELETE;

2. import javax.ws.rs.GET;

3. import javax.ws.rs.HeaderParam;

4. import javax.ws.rs.POST;

5. import javax.ws.rs.Path;

6. import javax.ws.rs.PathParam;

7. import javax.ws.rs.Produces;

8. import javax.ws.rs.QueryParam;

9. import javax.ws.rs.core.Response;

10.

11. import com.easyway.esb.mule.jersey.exception.HelloWorldException;

12.

13. /**

21. */

22. @Path("/helloworld")

23. public class HelloWorldResource

24. {

25. @POST

26. @Produces("text/plain")

27. public String sayHelloWorld()

28. {

29. return "Hello World";

30. }

31.

32. @GET

33. @Produces("application/json")

34. @Path("/sayHelloWithJson/{name}")

35. public HelloBean sayHelloWithJson(@PathParam("name") String name)

36. {

37. HelloBean hello = new HelloBean();

38. hello.setMessage("Hello " + name);

39. return hello;

40. }

41.

42. @DELETE

43. @Produces("text/plain")

44. public String deleteHelloWorld()

45. {

46. return "Hello World Delete";

47. }

48.

49. @GET

50. @Produces("text/plain")

51. @Path("/sayHelloWithUri/{name}")

52. public String sayHelloWithUri(@PathParam("name") String name)

53. {

54. return "Hello " + name;

55. }

56.

57. @GET

58. @Produces("text/plain")

59. @Path("/sayHelloWithHeader")

60. public Response sayHelloWithHeader(@HeaderParam("X-Name") String name)

61. {

62. return Response.status(201).header("X-ResponseName", name).entity("Hello " + name).build();

63. }

64.

65. @GET

66. @Produces("text/plain")

67. @Path("/sayHelloWithQuery")

68. public String sayHelloWithQuery(@QueryParam("name") String name)

69. {

70. return "Hello " + name;

71. }

72.

73. @GET

74. @Produces("text/plain")

75. @Path("/throwException")

76. public String throwException() throws HelloWorldException

77. {

78. throw new HelloWorldException("This is an exception");

79. }

80. }

2.多个资源的请求的并当使用:

Xml代码

1. <flow name="helloWorldResource">

3. <inbound-endpoint address="http://localhost:63081/" />

5. <jersey:resources>

6. <component class="org.mule.module.jersey.HelloWorldResource" />

7. <component class="org.mule.module.jersey.AnotherWorldResource" />

8. </jersey:resources>

9. </flow>

3.针对复杂数据类型的的解析处理

Xml代码

1. <flow name="helloWorldResource">

2. <inbound-endpoint address="http://localhost:63081/" exchange-pattern="request-response"/>

3. <jersey:resources>

4. <component class="com.easyway.esb.mule.jersey.HelloWorldResource"/>

5. <jersey:context-resolver class="com.easyway.esb.mule.jersey.contextresolver.JaxbCustomContextResolver" />

6. </jersey:resources>

7. </flow>

Java代码

1. import javax.ws.rs.ext.ContextResolver;

2. import javax.ws.rs.ext.Provider;

3. import javax.xml.bind.JAXBContext;

4. import javax.xml.bind.JAXBException;

6. import com.easyway.esb.mule.jersey.HelloBean;

7. import com.sun.jersey.api.json.JSONConfiguration;

8. import com.sun.jersey.api.json.JSONJAXBContext;

10. @Provider

11. public class JaxbCustomContextResolver implements ContextResolver<JAXBContext>

12. {

13. protected JAXBContext context;

14.

15. @Override

16. public JAXBContext getContext(Class<?> type)

17. {

18. if (type.equals(HelloBean.class))

19. {

20. if (context == null)

21. {

22. try

23. {

24. context = new JSONJAXBContext(JSONConfiguration.natural().build(), type);

25. }

26. catch (JAXBException e)

27. {

28. // do nothing

29. }

30. }

31. return context;

32. }

33. return null;

34. }

35. }

4.针对REST异常的处理绑定使用

Xml代码

1. <model name="BasicJerseyTest">

2. <service name="helloWorldResource">

3. <inbound>

4. <inbound-endpoint address="http://localhost:63081/" exchange-pattern="request-response"/>

5. </inbound>

6. <jersey:resources>

7. <component class="com.easyway.esb.mule.jersey.HelloWorldResource"/>

8. <jersey:exception-mapper class="com.easyway.esb.mule.jersey.exception.HelloWorldExceptionMapper" />

9. </jersey:resources>

10. </service>

11. </model>
