spring 获取自定义配置文件properties中参数

Spring中config属性文件的读取与使用 PropertyPlaceholderConfigurer 注解@Component

1.配置文件：/WEB-INF/configInfo.properties

配置文件内容：

email.host = www.94gleaner.com

email.port = xxx

email.username = gleaner

email.password = xxx

email.sendFrom = 94gleaner@94gleaner.com

2.Spring容器启动时，使用内置bean对属性文件信息进行加载，在bean.xml中添加如下：

<!– spring的属性加载器，加载properties文件中的属性 –>

<bean id=”propertyConfigurer” class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”>

<property name=”location”>

<value>/WEB-INF/configInfo.properties</value>

</property>

<property name=”fileEncoding” value=”utf-8″ />

</bean>

3.其它bean中引用,例：

<property name=”host”>

<value>${email.host}</value>

</property>

<property name=”port”>

<value>${email.port}</value>

</property>

4.JAVA代码中获取方法：创建ConfigInfo.java

@Component(“configInfo”)

public class ConfigInfo {

@Value(“${email.host}”)

private String host;

@Value(“${email.port}”)

private String port;

public String getHost() {

return host;

}

public String getPort() {

return port;

}

}

5.代码中调用处

@Autowired

private ConfigInfo configInfo;

public byte[] Test(HttpServletResponse response) {

string host = configInfo.getHost();

}
