春天避免使用bean：beans而是编写bean？

Question

This is working:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-3.0.xsd">

    <beans:bean id="test2" name="name" class="org.chicago.home.Test2"> </beans:bean>

    <beans:bean id="test1" class="org.chicago.home.Test1">
        <beans:constructor-arg ref="test2"/>
    </beans:bean>
</beans:beans>

This is not. But, I find this type of configuration better. What should I do to the namespace to make this below configuration work?

Also, can I pass idref in constructor-arg? That doesn't seem to work for me. Neither idref bean="" nor idref local="" inside constructor-arg is working.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-3.0.xsd">

    < I am pressing Ctrl + Space here, but it says beans doesn't have any child tags. 

</beans>

Answer 1

You can use something like:

<beans xmlns="http://www.springframework.org/schema/beans"

Example here

For inject constuctor, you can use:

<constructor-arg><ref bean="anotherExampleBean"/></constructor-arg>

Spring documentation for inject constructor

Answer 2

It looks like you might have a typo in the second version. I think this:

<beans:xmlns="http://www.springframework.org/schema/security"

should be this:

<beans xmlns="http://www.springframework.org/schema/security"

Unless you just copied it wrong. If this doesn't fix it, can you post the error message?
