Injecting Configuration

The following example uses a properties file:

jdbcSettings.jdbcDriver   = com.mysql.jdbc.Driver
jdbcSettings.jdbcURL      = jdbc:mysql://127.0.0.1:3306/test
jdbcSettings.userName     = sa
jdbcSettings.userPassword =

The same configuration can also be expressed in XML:

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="http://www.hasor.net/sechma/main">
    <jdbcSettings>
        <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver>
        <jdbcURL>jdbc:mysql://127.0.0.1:3306/test</jdbcURL>
        <userName>sa</userName>
        <userPassword></userPassword>
    </jdbcSettings>
</config>

In a bean, use the net.hasor.core.InjectSettings annotation to indicate that the injected value comes from the configuration file.

Example

public class DataBaseBean {
    @InjectSettings("jdbcSettings.jdbcDriver")
    private String jdbcDriver;

    @InjectSettings("jdbcSettings.jdbcURL")
    private String jdbcURL;

    @InjectSettings("jdbcSettings.userName")
    private String user;

    @InjectSettings("jdbcSettings.userPassword")
    private String password;

    ...
}

Finally, specify the configuration file to load when creating the container.

AppContext appContext = Hasor.create().mainSettingWith("<config-file-name>").build();

Automatic Type Conversion

@InjectSettings can perform simple type conversion. The conversion utility is net.hasor.cobble.convert.ConverterUtils.

public class TestBean {
    @InjectSettings("userInfo.myAge")
    private int myAge;
}
