文件参数shell命令注入 springmvc spring带参数注入

一，Spring注入参数-bean
1，在com.cruise.entity包下新建Dao类，属性name，

package com.cruise.entity;
public class Dog {
     private String name;
     public String getName() {
        return name;
     }
     public void setName(String name) {
        this.name = name;
     }
 }

2，修改People属性，增加Dog属性，重新生成get 和set 方法，修改toString()方法，

@Override
     public String toString() {
        return "People [id=" + id + ", name=" + name + ", age=" + age + ", dog=" + dog.getName() + "]";
     }

3，在beans.xml中定义id为dog1，注入属性值。定义id为people2，注入属性值，

<bean id="dog1" class="com.cruise.entity.Dog">
     <property name="name" value="Jack">property>
 bean>

 <bean id="people2" class="com.cruise.entity.People">
     <property name="id" value="1">property>
     <property name="name" value="张三">property>
     <property name="age" value="11">property>
     <property name="dog" ref="dog1">property>
 bean>

4，Test类中添加测试方法test2()，运行-测试

@Test
     public void test2() {
        People people2 = (People)CPXAC.getBean("people2");
        System.out.println(people2);
     }

二，Spring注入参数-内部bean
1，在beans.xml中添加代码，定义people3，注入属性值，添加内部bean，

<bean id="people3" class="com.cruise.entity.People">
     <property name="id" value="1">property>
     <property name="name" value="张三">property>
     <property name="age" value="11">property>
     <property name="dog" >
        <bean class="com.cruise.entity.Dog">
            <property name="name" value="Tom">property>
        bean>
     property>
 bean>

2，在Test中添加测试方法test3()，运行-测试

@Test
     public void test3() {
        People people3 = (People)CPXAC.getBean("people3");
        System.out.println(people3);
     }

三，Spring注入参数-null标签bean
1，在beans.xml中添加代码，定义people4，注入属性值null标签，添加内部bean，

<bean id="people4" class="com.cruise.entity.People">
     <property name="id" value="1">property>
     <property name="name" value="张三">property>
     <property name="age" value="11">property>
     <property name="dog" >
        <null>null>
     property>
 bean>

3，修改People类中的toString()方法，否则会报空指针异常

@Override
     public String toString() {
        return "People [id=" + id + ", name=" + name + ", age=" + age + ", dog=" + dog + "]";
     }

2，在Test中添加测试方法test4()，运行-测试

@Test
     public void test4() {
        People people3 = (People)CPXAC.getBean("people4");
        System.out.println(people3);
     }

四，Spring注入参数-级联属性参数
1，在beans.xml中添加代码，定义people5，注入属性值，添加内部bean，

<bean id="people5" class="com.cruise.entity.People">
     <property name="id" value="1">property>
     <property name="name" value="张三">property>
     <property name="age" value="11">property>
     <property name="dog.name" value="Jack2">property>
 bean>

2，修改People类中的Dog属性，修改toString，

private Dog dog=new Dog();
 @Override
     public String toString() {
        return "People [id=" + id + ", name=" + name + ", age=" + age + ", dog=" + dog.getName() + "]";
     }

3，在Test中添加测试方法test5()，运行-测试，测试之后还原People类dog属性写法，注释掉beans.xml中的people5.以防干扰。

@Test
     public void test5() {
        People people5 = (People)CPXAC.getBean("people5");
        System.out.println(people5);
     }

     public String toString() {
        return "People [id=" + id + ", name=" + name + ", age=" + age + ", dog=" + dog.getName() + ", hobbies=" + hobbies + "]";
     }

2，在beans.xml中添加代码，定义people6，注入属性值，添加内部bean，将id为people5的bean注释掉，

<bean id="dog1" class="com.cruise.entity.Dog">
     <property name="name" value="Jack"></property>
 </bean>
  ……

 </bean>

3，在Test中添加测试方法test6()，运行-测试，

@Test
     public void test6() {
        People people5 = (People)CPXAC.getBean("people6");
        System.out.println(people5);
     }
