Spring配置参考资料

Spring简单用例所需jarSpring配置问题注意一：注入beanXML文件源码（文件的标头）<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans.xsd"> <beanid="hello"class=".HelloWord"></bean> <beanid="student"class=".Student"></bean> <beanid="studentService"class=".StudentService"> <propertyname="jk"ref="student"></property> </bean></beans>配置中的ref指定的是Bean注意二：属性注入属性注册，顺序可改变注意三：重写toString方法使用直接输出时需要重写toString方法。注意四：构造方法注入之类型注入参数的顺序不可以改变；此处有个几个参数就找几个参数的构造方法Exceptioninthread"main"org.springframework.beans.factory.BeanCreationException:Errorcreatingbeanwithname'peoper3'definedinclasspathresource[beans.xml]:Couldnotresolvematchingconstructor(hint:specifyindex/type/nameargumentsforsimpleparameterstoavoidtypeambiguities)如报此错误是：类中没有有参构造方法！注意五：构造方法注入控制台错误及原因Exceptioninthread"main"org.springframework.beans.factory.BeanCreationException:Errorcreatingbeanwithname'peoper'definedinclasspathresource[beans.xml]:Instantiationofbeanfailed;nestedexceptionisorg.springframework.beans.BeanInstantiationException:Couldnotinstantiatebeanclass[com.zx.entity.Peoper]:Nodefaultconstructorfound;nestedexceptionisjava.lang.NoSuchMethodException:com.zx.entity.Peoper.<init>()原因是缺少无参构造方法注意六：构造方法注入之顺序注入注意：顺序从0开始，顺序注入可添加类型格式。注意七：工厂方法注入之动态注入创建工厂类及方法。 结果：注意八：工厂方法注入之静态注入注意九：注入参数之bean间的嵌套（注入bean）注意十：注入参数之内部bean注意十一：集合注入ListSetMap系统配置propertiesSpring自动装配通过配置default-autowire属性，SpringIOC容器可以自动为程序注入bean；默认default，no,不启动自动装配按照名称装配注意一：按照名称装配必须跟类中的名称匹配起来按照类型装配注意一：按照类型装配问题：原因是存在两个类型一样的！注意二：按类型装配（id问题）此处的id可不与类中的名一致！按照构造方法装配注意一：按构造方法装配（id问题）此处的id可不与类中的名一致！方法注入Springbean作用默认是单例，通过配置prototype实现多利方法注入lookup-methodBean之间的关系继承Parent属性依赖未添加依赖：添加依赖：依赖属性depends-on引用如spring配置注意九Bean的作用范围参数：scope默认singletonSpringioc容器中仅有一个bean实例，bean以单例的方式存在Prototype每次从容器中调用Bean时，都产生一个新的实例。SpringAOP实例实例一：前置通知ServiceAspect接口及实现类ServiceAspectIplPeopleService接口及实现类PeopleServiceIpl<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:aop="/schema/aop"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans.xsd/schema/aop/schema/aop/spring-aop-2.0.xsd"> <beanid="peopleService"class="com.zx.service.ipl.PeopleServiceIpl"></bean> <beanid="serviceAspect"class="com.zx.service.ipl.ServiceAspectIpl"></bean> <!-- 设置千面切入点--> <aop:config> <!-- 将serviceAspect切入进peopleService--> <aop:aspectid="serviceAspect"ref="serviceAspect"> <aop:pointcutexpression="execution(*com.zx.service.*.*(..))"id="aspect"/> <aop:beforemethod="add"pointcut-ref="aspect"/> </aop:aspect> </aop:config></beans>启动报错及原因原因：缺少jar包AOP所需的jar包获取切点的类及方法名后置通知环绕通知异常通知Spring对JDBC的支持Xml标头引入命名空间：<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans" xmlns:context="/schema/context"xmlns:xsi="/2001/XMLSchema-instance"xmlns:aop="/schema/aop"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans.xsd/schema/aop/schema/aop/spring-aop-2.0.xsd/schema/context/schema/context/spring-context-2.5.xsd"></beans>数据源代码XML文件代码：<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans" xmlns:context="/schema/context"xmlns:xsi="/2001/XMLSchema-instance"xmlns:aop="/schema/aop"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans.xsd/schema/aop/schema/aop/spring-aop-2.0.xsd/schema/context/schema/context/spring-context-2.5.xsd"><!--加载指定路径properties--><context:property-placeholderlocation="classpath:perties"/> <!--数据源--><beanid="dataSource"class="mons.dbcp.BasicDataSource"destroy-method="close"><propertyname="driverClassName"value="${driverClassName}"/><propertyname="url"value="${url}"/><propertyname="username"value="${username}"/><propertyname="password"value="${password}"/></bean></beans>此处用到了dbcp的连接池！数据源代码所需要的jar包数据源链接driverClassName=oracle.jdbc.driver.OracleDriverurl=jdbc:oracle:thin:@localhost:1521:ORCLusername=scottpassword=tiger数据源链接所需的jar包添加oracle驱动jdbc所用到的包使用Jdbctemplate对象来完成jdbc操作<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans" xmlns:context="/schema/context"xmlns:xsi="/2001/XMLSchema-instance"xmlns:aop="/schema/aop"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans.xsd/schema/aop/schema/aop/spring-aop-2.0.xsd/schema/context/schema/context/spring-context-2.5.xsd"><!--加载指定路径properties--><context:property-placeholderlocation="classpath:perties"/> <!--数据源--><beanid="dataSource"class="mons.dbcp.BasicDataSource"destroy-method="close"><propertyname="driverClassName"value="${driverClassName}"/><propertyname="url"value="${url}"/><propertyname="username"value="${username}"/><propertyname="password"value="${password}"/></bean><!--使用Jdbctemplate对象来完成jdbc操作--><beanid="jdbcTemplate"class
