Spring 在配置中使用*.properties

xml

<?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:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.0.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-3.0.xsd">
    <context:annotation-config/>
    
    <context:component-scan base-package="com.web.spring.other" />

    <bean class="com.web.spring.other.AppConfig"/>
访法一
   <context:property-placeholder location="classpath:jdbc.properties" />
     方法二
    <util:properties id="jdbcProperties" location="classpath:jdbc.properties"/>
</beans>

实现一

package com.web.spring.other;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

@Configuration
@ImportResource("classpath*:spring/spring-properties.xml")
public class AppConfig {
    private @Value("${jdbc.driverClassName}") String driverClassName;
    @Bean(initMethod = "init")
    public JDBCBean jdbc(){
        JDBCBean jdbc=new JDBCBean();
        jdbc.setDriverClassName(driverClassName);
        return jdbc;
    }

}

jdbc.driverClassName=org.hsqldb.jdbcDriver

实现二

package com.web.spring.other;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig {
    private @Value("#{jdbcProperties.driverClassName}") String driverClassName;
   //private @Value("#{jdbcProperties['jdbc.driverClassName']}") String driverClassName;
    @Bean(initMethod = "init")
    public JDBCBean jdbc(){
        JDBCBean jdbc=new JDBCBean();
        jdbc.setDriverClassName(driverClassName);
        return jdbc;
    }

}

driverClassName=org.hsqldb.jdbcDriver
