springMVC+Hibernate配置

本文描述下 sypro 项目中使用 springMVC+Hibernate配置，初学SpringMVC做下简单整理解。

1.web项目首先我们要使用 web.xml文件将 spring配置引入进来

1. <?xml version="1.0" encoding="UTF-8"?>
2. <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
5. <description>springMvc+hibernate4+easyui</description>
6. <display-name>sypro2.02</display-name>
7. <context-param>
8. <param-name>contextConfigLocation</param-name>
9. <param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-ehcache.xml,classpath:spring-apacheFtpServer.xml</param-value>
10. </context-param>
11. <filter>

34. <filter-name>encodingFilter</filter-name>
35. <url-pattern>/*</url-pattern>
36. </filter-mapping>
37. <listener>

45. <listener>
46. <description>Introspector缓存清除监听器</description>
47. <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>

49. <servlet>
50. <description>spring mvc servlet</description>
51. <servlet-name>springMvc</servlet-name>
52. <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

59. </servlet>

61. <servlet-name>springMvc</servlet-name>
62. <url-pattern>*.do</url-pattern>
63. </servlet-mapping>
64. <session-config>

66. </session-config>
67. <welcome-file-list>

71. <error-page>

73. <location>/error/404.jsp</location>
74. </error-page>
75. <error-page>
76. <error-code>500</error-code>
77. <location>/error/500.jsp</location>
78. </error-page>
79. <distributable />
80. </web-app>

部署applicationContext的xml文件，如果在web.xml中不写任何参数配置信息，默认的路径是”/WEB-INF
/applicationContext.xml，在WEB-INF目录下创建的xml文件的名称必须是applicationContext.xml。
如果是要自定义文件名可以在web.xml里加入contextConfigLocation如下，在<param-value>
</param-value>里指定相应的xml文件名，如果有多个xml文件，可以写在一起并一“,”号分隔

1. <display-name>sypro2.02</display-name>
2. <context-param>
3. <param-name>contextConfigLocation</param-name>
4. <param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-ehcache.xml,classpath:spring-apacheFtpServer.xml</param-value>
5. </context-param>
6. <filter>
7. <filter-name>openSessionInViewFilter</filter-name>
8. <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
9. <init-param>
10. <param-name>singleSession</param-name>
11. <param-value>true</param-value>
12. </init-param>
13. </filter>

加载contextConfigLocation则交给监听来实现

1. <listener>
2. <description>spring监听器</description>
3. <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
4. </listener>

然后配置springMVC处理请求映射

1. <servlet>
2. <description>spring mvc servlet</description>
3. <servlet-name>springMvc</servlet-name>
4. <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
5. <init-param>
6. <description>spring mvc 配置文件</description>
7. <param-name>contextConfigLocation</param-name>
8. <param-value>classpath:spring-mvc.xml</param-value>
9. </init-param>
10. <load-on-startup>1</load-on-startup>
11. </servlet>
12. <servlet-mapping>
13. <servlet-name>springMvc</servlet-name>
14. <url-pattern>*.do</url-pattern>
15. </servlet-mapping>

2.applicationContext.xml 文件常用配置，在该项目中使用的自定义写法 将
applicationContext.xml 重命名为： spring-mvc.xml
,注意如果不使用自定义写法applicationContext.xml则存放在
/WEB-INF/applicationContext.xml目录且不可重命名

applicationContext.xml （spring-mvc.xml） 常用配置如下：

1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
5. xsi:schemaLocation="http://www.springframework.org/schema/beans
6. http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

8. http://www.springframework.org/schema/context/spring-context-3.0.xsd

10. http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
11. <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
12. <context:component-scan base-package="sy.controller" />
13. <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
14. <bean id="mappingJacksonHttpMessageConverter"
15. class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
16. <property name="supportedMediaTypes">
17. <list>

21. </bean>

35. <bean id="multipartResolver"

37. <property name="defaultEncoding">

43. <property name="maxInMemorySize">
44. <value>4096</value>
45. </property>
46. </bean>
47. <!-- 拦截器 -->
48. <mvc:interceptors>
49. <mvc:interceptor>
50. <mvc:mapping path="/**" />
51. <bean class="sy.interceptors.EncodingInterceptor" />
52. </mvc:interceptor>
53. <mvc:interceptor>
54. <mvc:mapping path="/**" />
55. <bean class="sy.interceptors.AuthInterceptor" />
56. </mvc:interceptor>
57. </mvc:interceptors>
58. </beans>

spring-xml:

1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
4. xsi:schemaLocation="

9. ">
10. <!-- 引入属性文件 -->
11. <context:property-placeholder location="classpath:config.properties" />
12. <!-- 自动扫描dao和service包(自动注入) -->
13. <context:component-scan base-package="sy.dao,sy.service" />
14. </beans>

1. <!-- 引入属性文件 -->
2. <context:property-placeholder location="classpath:config.properties" />

项目配置映入属性文件在配置hibenrate数据库配置提供了便利

如下 spring-hibernate.xml 配置

1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
