Get Properties profile by annotations in SPRINGMVC

In a SPRINGMVC project, you get the configuration in the properties configuration file by annotating @value, using the package that the annotation must introduce:

Spring-beans-4.1.4.release.jar

Here's what you need to configure in spring's configuration file

<?xml version= "1.0" encoding= "UTF-8"?><Beans xmlns="Http://www.springframework.org/schema/beans"    Xmlns:xsi="Http://www.w3.org/2001/XMLSchema-instance"    Xmlns:context="Http://www.springframework.org/schema/context"    Xmlns:tx="Http://www.springframework.org/schema/tx"    XMLNS:AOP="HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"    xsi:schemalocation="Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/TX http://www.springframework.org/schema/tx/spring-tx-3.0.xsd/HTTP WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP http://www.springframework.org/schema/aop/spring-aop-3.0.xsd/HTTP Www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd " >    <bean id= "configproperties" class=" Org.springframework.beans.factory.config.PropertiesFactoryBean ">        < property name="Locations">            <list>                <value>Classpath*:config/autocreatetable.properties</value>            </list>        </Property >    </Bean>    <bean id= "propertyconfigurer" class=" Org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer ">        < property name="Properties" ref="Configproperties" / >    </Bean></Beans>

After configuring the above configuration, you can take this in your code:

    /**     * 要扫描的model所在的pack     */    @Value("#{configProperties[‘mybatis.model.pack‘]}")     private String pack;    /**     * 自动创建模式：update表示更新，create表示删除原表重新创建     */    @Value("#{configProperties[‘mybatis.table.auto‘]}")    private String tableAuto;

Configproperties is the value in the Bean's id,["] is the key in the configuration file to be taken, so that the value in the configuration file can be mapped to the pack, Tableauto attribute in the code.
