Method Detail

getContextLocation

protected String getContextLocation()

autowire

protected void autowire()

Autowire this instance using its associated application context. This may be invoked by runInContext(java.lang.String[]) to autowire this bean using its associated context.

For this to work, the application context must have autowiring enabled, e.g., via <context:annotation-config/>.
