JavaBean Getting Started (3) SetProperty setting and getting properties

About SetProperty settings

The <jsp:setProperty> property settings can be grouped into four categories:

1. Automatic matching: <jsp:setproperty name= "instantiated object name (ID)" property= "*"/>

2. Specify properties: <jsp:setproperty name= "instantiated object name (ID)" property= "Property name"/>

3. Specify parameters: <jsp:setproperty name= "instantiated object name (ID)" property= "Property name" param= "parameter name"/>

4. Specify content: <jsp:setproperty name= "instantiated object name (ID)" property= "Property name" value= "Content"/>

Example shows the application of four kinds of settings

We are also the procedures in the above article to verify.
