spring1 配置方式注入

第一步：jar包。maven的pom文件

      

<dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.0.2.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.0.2.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>4.0.2.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>4.0.2.RELEASE</version>    </dependency>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.9</version>    </dependency>

大概这么多。下面是基本的代码

实体类

package com.demo.student;import java.util.List;import java.util.Map;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.stereotype.Service;public class Student {   private String name;    private List<String> list;private Map<String,Object> map;private Teacher teacher;public String getName() {return name;}public void setName(String name) {this.name = name;}public List<String> getList() {return list;}public void setList(List<String> list) {this.list = list;}public Map<String, Object> getMap() {return map;}public void setMap(Map<String, Object> map) {this.map = map;}public Teacher getTeacher() {return teacher;}public void setTeacher(Teacher teacher) {this.teacher = teacher;}@Overridepublic String toString() {return "Student [name=" + name + ", list=" + list + ", map=" + map+ ", teacher=" + teacher + "]";}   }

package com.demo.student;import org.springframework.stereotype.Repository;public class Teacher {    public void stu(){System.out.println("Teacher");}}

<?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          http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        "         xmlns:context="http://www.springframework.org/schema/context"            >                               <!-- 扫描包 -->        <context:component-scan base-package="com.demo.listaotowired"/>        <bean id="teacher" class="com.demo.student.Teacher"></bean>         <bean id="student" class="com.demo.student.Student">            <property name="name" value ="hello"></property>            <property name="teacher" ref="teacher"></property>            <property name="list">               <list>                   <value>1</value>                   <value>2</value>               </list>            </property>            <!-- map注入-->            <property name="map">               <map>                  <entry key="first" value="first"></entry>               </map>            </property>         </bean>                                         </beans>

Test代码

package springDemo;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.demo.student.Student;@RunWith(value=SpringJUnit4ClassRunner.class)@ContextConfiguration("classpath:beans.xml")public class TestAutoired {   @Autowiredprivate Student student;@Testpublic void test(){System.out.println(student);}}

输入内容

Student [name=hello, list=[1, 2], map={first=first}, teacher=com.demo.student.Teacher@1d387200]
