Spring的MVC可不可以和Struts在同一个Context下使用?

zhirenshao 2005-06-12 09:42:38
我在同一个web application下可不可以同时使用Spring的MVC和Struts?

比如我在web.xml里配,让 .do 的request都去struts的ActionServlet, .form的request都去spring的controller,可以这样吗?

本人用的框架就是struts+spring+hibernate的

但是如果没有框架,一旦开发大一点的系统,你就很郁闷了

这样做是不是自找麻烦,为什么不用统一简单的架构,非要混合使用,虽然每种架构都不完美,但为了开发和维护方便,我认为大体框架风格要一致

阿敏, 每次我的疑难贴都有你回,谢谢。 (而且每次我的疑难贴总共都没几个人回,所以你都有很多分)
弃用了struts,用spring mvc框架做了几个项目,感觉都不错,而且使用了注解方式,可以省掉一大堆配置文件。本文主要介绍使用注解方式配置的spring mvc,之前写的spring3.0 mvc和rest小例子没有介绍到数据层的内容,现在这一篇补上。下面开始贴代码。 文中用的框架版本:spring 3,hibernate 3,没有的,自己上网下。 先说web.xml配置: [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02. 03. s3h3 04. <context-param> 05. contextConfigLocation 06. classpath:applicationContext*.xml 07. context-param> 08. 09. org.springframework.web.context.ContextLoaderListener 10. 11. 12. 13. spring 14. org.springframework.web.servlet.DispatcherServlet 15. 1 16. 17. 18. spring <!-- 这里在配成spring,下边也要写一个名为spring-servlet.xml的文件,主要用来配置它的controller --> 19. *.do 20. 21. 22. index.jsp 23. 24. spring-servlet,主要配置controller的信息 [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02. context="http://www.springframework.org/schema/context" 05. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 06. http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 07. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 08. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 09. 10. <context:annotation-config /> 11. <!-- 把标记了@Controller注解的类转换为bean --> 12. <context:component-scan base-package="com.mvc.controller" /> 13. <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 --> 14. 15. 16. <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 --> 17. 19. 20. 23. applicationContext.xml代码 [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02.context="http://www.springframework.org/schema/context" 04. xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" 05. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 06. xsi:schemaLocation=" 07. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 08. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd 09. http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 10. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> 11. 12. <context:annotation-config /> 13. <context:component-scan base-package="com.mvc" /> <!-- 自动扫描所有注解该路径 --> 14. 15. <context:property-placeholder location="classpath:/hibernate.properties" /> 16. 17. 19. 20. 21. 22. ${dataSource.dialect} 23. ${dataSource.hbm2ddl.auto} 24. update 25. 26. 27. 28. 29. com.mvc.entity<!-- 扫描实体类,也就是平时所说的model --> 30. 31. 32. 33. 34. 36. 37. 38. 39. 40. 42. 43. 44. 45. 46. 47. <!-- Dao的实现 --> 48. 49. 50. 51. 52. 53. 54. 55. hibernate.properties数据库连接配置 [java] view plaincopy 01.dataSource.password=123 02.dataSource.username=root 03.dataSource.databaseName=test 04.dataSource.driverClassName=com.mysql.jdbc.Driver 05.dataSource.dialect=org.hibernate.dialect.MySQL5Dialect 06.dataSource.serverName=localhost:3306 07.dataSource.url=jdbc:mysql://localhost:3306/test 08.dataSource.properties=user=${dataSource.username};databaseName=${dataSource.databaseName};serverName=${dataSource.serverName};password=${dataSource.password} 09.dataSource.hbm2ddl.auto=update 配置已经完成,下面开始例子 先在数据库建表,例子用的是mysql数据库 [java] view plaincopy 01.CREATE TABLE `test`.`student` ( 02. `id` int(10) unsigned NOT NULL AUTO_INCREMENT, 03. `name` varchar(45) NOT NULL, 04. `psw` varchar(45) NOT NULL, 05.

23. 24.</form> 25.</body> 26.</html> controller类实现,只需把注解写上,spring就会自动帮你找到相应的bean,相应的注解标记意义,不明白的,可以自己查下@Service,@Controller,@Entity等等的内容。 [java] view plaincopy 01.package com.mvc.controller; 02. 03.import java.util.List; 04. 05.import javax.servlet.http.HttpServletRequest; 06.import javax.servlet.http.HttpServletResponse; 07. 08.import org.apache.commons.logging.Log; 09.import org.apache.commons.logging.LogFactory; 10.import org.springframework.beans.factory.annotation.Autowired; 11.import org.springframework.stereotype.Controller; 12.import org.springframework.ui.ModelMap; 13.import org.springframework.web.bind.annotation.RequestMapping; 14.import org.springframework.web.bind.annotation.RequestMethod; 15.import org.springframework.web.bind.annotation.RequestParam; 16.import org.springframework.web.servlet.ModelAndView; 17. 18.import com.mvc.entity.Student; 19.import com.mvc.service.StudentService; 20. 21.@Controller 22.@RequestMapping("/student.do") 23.public class StudentController { 24. protected final transient Log log = LogFactory 25. .getLog(StudentController.class); 26. @Autowired 27. private StudentService studentService; 28. public StudentController(){ 29. 30. } 31. 32. @RequestMapping 33. public String load(ModelMap modelMap){ 34.

Student st = new Student(); 67. st.setId(Integer.valueOf(id)); 68. studentService.delete(st); 69. response.getWriter().print("{/"del/":/"true/"}"); 70. } 71. catch(Exception e){ 72. log.error(e.getMessage()); 73. e.printStackTrace(); 74. } 75. } 76.} service类实现 [java] view plaincopy 01.package com.mvc.service; 02. 03.import java.util.List; 04. 05.import org.springframework.beans.factory.annotation.Autowired; 06.import org.springframework.stereotype.Service; 07.import org.springframework.transaction.annotation.Transactional; 08. 09.import com.mvc.dao.EntityDao; 10.import com.mvc.entity.Student; 11. 12.@Service 13.public class StudentService { 14. @Autowired 15. private EntityDao entityDao; 16. 17. @Transactional 18. public List<Object> getStudentList(){ 19. StringBuffer sff = new StringBuffer(); 20. sff.append("select a from ").append(Student.class.getSimpleName()).append(" a "); 21. List<Object> list = entityDao.createQuery(sff.toString()); 22. return list; 23. } 24. 25. public void save(Student st){ 26. entityDao.save(st); 27. } 28. public void delete(Object obj){ 29. entityDao.delete(obj); 30. } 31.} OK,例子写完。有其它业务内容,只需直接新建view,并实现相应comtroller和service就行了,配置和dao层的内容基本不变,也就是每次只需写jsp(view),controller和service调用dao就行了。 怎样,看了这个,spring mvc是不是比ssh实现更方便灵活。
