Spring项目XML文件使用小结

2022-11-13 12:11:46 文件 项目 小结

1 项目pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="Http://Maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.yang</groupId>
    <artifactId>spring-study</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>spring-01-ioc1</module>
        <module>spring-02-hellpspring</module>
        <module>spring-04-di</module>
        <module>spring-06-autowired</module>
        <module>spring-07-annotation</module>
    </modules>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-WEBmvc</artifactId>
            <version>5.1.4.RELEASE</version>
        </dependency>
    </dependencies>

</project>

2 项目初始IOC容器

```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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       https://www.springframework.org/schema/beans/spring-beans.xsd">
    <!-- more bean definitions Go here -->
</beans>
···

3 项目需要自动装配

```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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">
    <context:annotation-config/>
    <bean id="dog" class="com.yang.pojo.Dog"></bean>
    <bean id="cat" class="com.yang.pojo.Cat"></bean>
    <bean id = "people" class="com.yang.pojo.People">
          <property name="cat" ref="cat"/>
        <property name="dog" ref="dog"/>
        <property name="name" value="张3"/>
    </bean>
</beans>

增加的点：
1 xmlns:context="http://www.springframework.org/schema/context"等等头文件

2 context:annotation-config/

4 项目需要注解

<?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:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
       https://www.springframework.org/schema/aop/spring-aop.xsd">
<!--    指定要扫描的包，包下面的注解才能够生效-->
<context:component-scan base-package="com.yang.pojo"/>
<!--    注解驱动-->
    <context:annotation-config/>
</beans>

增加的点：

<context:component-scan base-package=“com.yang.pojo”/>

https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
