spring配置问题

[dunerunner]

web.xml

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-mvc.xml,classpath:spring-mybatis.xml</param-value>
	</context-param>

	<servlet>
		<servlet-name>spring mvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-base.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring mvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

spring-base.xml

	<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="ignoreResourceNotFound" value="true" />
		<property name="fileEncoding">
			<value>UTF-8</value>
		</property>
		<property name="locations">
			<list>
				<value>classpath:*.properties</value>
			</list>
		</property>
	</bean>

spring-mvc.xml

	<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>application/json;charset=UTF-8</value>
				<value>text/html;charset=UTF-8</value>
			</list>
		</property>
	</bean>

	<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
	<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="mappingJacksonHttpMessageConverter" />
			</list>
		</property>
	</bean>

	<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
		<property name="basenames">
			<list>
				<value>classpath:messages</value>
			</list>
		</property>
		<property name="defaultEncoding" value="UTF-8" />
		<property name="useCodeAsDefaultMessage" value="true" />
	</bean>
	<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
		<property name="defaultLocale" value="zh_CN" />
	</bean>

	<context:component-scan base-package="test" />

	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>

spring-mybatis.xml

	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
		<property name="driverClass" value="${jdbc.driver}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource">
			<ref local="dataSource" />
		</property>
	</bean>

TestController

@Controller
@RequestMapping("/testPath")
public class TestController {

	@RequestMapping(value = "/testAction")
	public String doTest(HttpServletRequest request, HttpServletResponse response, String param) {
		System.err.println(request.getParameter("param"));
		ComboPooledDataSource dataSource = ContextLoader.getCurrentWebApplicationContext().getBean("dataSource", ComboPooledDataSource.class);
		System.err.println(dataSource.getJdbcUrl());
		return "/index";
	}

}

System.err.println(dataSource.getJdbcUrl());
输出的是
${jdbc.url}

web.xml中改为

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-base.xml,classpath:spring-mybatis.xml</param-value>
	</context-param>

	<servlet>
		<servlet-name>spring mvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>spring mvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

再输出就没问题了(把spring-base.xml放到context-param中)
jdbc:mysql://localhost:3306/mydb
求大神帮忙
所有分数献上

帮你顶一下吧 说实话我没看完太多了

[尼古拉斯-全蛋]

问题是啥，看的有点晕

[什么都不能]

你的web.xml里是不是还有个spring初始化的listener？<context-param>是给listener用的，没有配置占位符解析器，吧spring-base.xml 放到conext-param里

楼主没有加上spring-base.xml
