篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Spring 配置和集成相关的知识,希望对你有一定的参考价值。
1 创建web工程
使用eclipse创建一个web工程,加入工程修改为支持web3.1,具体的步骤将看到我发表
maven安装配置
2 spring配置

spring配置文件
spring-bean.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:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

</beans>
<bean id="demo" class="org.lisen.springdemo.model.Demo">
<property name="name">
<value>张三</value>
</property>
</bean>
配置文件说明:
属性 :
-
id:在容器中查找Bean的id(唯一、且不能以/开头)
-
class:bean的完整类名
-
name:在容器中查找Bean的名字(唯一、允许以/开头、允许多个值,多个值之间用逗号或空格隔开)
-
scope:(singleton|prototype)默认是singleton
singleton: 单例模式, 在每个Spring IoC容器中一个bean定义对应一个对象实例
prototype: 原型模式/多例模式, 一个bean定义对应多个对象实例 -
parent:指定一个父bean(必须要有继承关系才行)
-
abstract: 将一个bean定义成抽象bean(抽象bean是不能实例化的),抽象类一定要定义成抽象bean,非抽象类也可以定义成抽象bean
-
init-method=“init” 初始化调用对象的init方法
-
ref 引用
标签:
属性的配置
//<bean></bean>是javaBean
//<property></<property> 找属性名赋值
//<value>值</value>
<bean id="test" class="实体类全限类名">
<property name="name">

</property>
//<constructor-arg></<constructor-arg>找有参数构造方法赋值
<constructor-arg name="name">

复杂属性的配置
//复杂属性的配置

//ref 引用
<property name="addr" ref="addr"/>
