Loading Properties file is giving weird behavior

Consider this example

 public class EmailSender {    
 private Properties emailProperties;
 public Properties getEmailProperties() {
    return emailProperties;
  }

  public void setEmailProperties(Properties emailProperties) {
    this.emailProperties = emailProperties;
  }

In applicationContext.xml I have something like 

<bean name="emailSender" class="com.api.email.EmailSender">
    <property name="emailProperties" value="classpath*:email.properties"/>
</bean>

When I debug whats get set, I see

enter image description here

How do I load Properties for emailProperties?

The way you assign the property file seems incomplete. I normally use the util functions. Add this to your context xml file namespace:

xmlns:util="http://www.springframework.org/schema/util"

Then declare your property file:

<util:properties
    id="emailProperties"
    location="classpath:/app.properties"/>

And set the bean value:

<bean name="emailSender" class="com.api.email.EmailSender">
    <property name="emailProperties" ref="emailProperties"/>
</bean>

Maybe things have been simplified in Spring 4, but that's how you do it in 3 and earlier. it's a teensy bit shorter than using org.springframework.beans.factory.config.PropertiesFactoryBean.

Another solution:

<context:property-placeholder  location="classpath*:email.properties" />

<bean class="com.test.EmailSender" >
    <property name="prop1" value="${mail.prop1}" />
    <property name="prop2" value="${mail.prop2}" />
</bean>

- 

public class EmailSender {

    private String prop1;
    private String prop2;

    public String getProp1() {
        return prop1;
    }

    public void setProp1(String prop1) {
        this.prop1 = prop1;
    }

    public String getProp2() {
        return prop2;
    }

    public void setProp2(String prop2) {
        this.prop2 = prop2;
    }
}

I had to inject another bean which knows how to resolve Properties. The following worked for me

<bean id="emailProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="location" value="classpath:email.properties"/>
</bean>

<bean name="emailSender" class="com.api.email.EmailSender">
    <property name="emailProperties" ref="emailProperties"/>
</bean>
