### Question:
OverridablePropertyPlaceholderConfigurer extends PropertyPlaceholderConfigurer { public Map<String, String> getResolvedProps() { return Collections.unmodifiableMap(resolvedProps); }  @Override void setLocation(Resource location); void setSystemPropertyName(String systemPropertyName); String getSystemPropertyName(); Map<String, String> getResolvedProps();  }### Answer:
@Test public void testGetResolvedProps() { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-test.xml"); final OverridablePropertyPlaceholderConfigurer portalPropertyPlaceholder = (OverridablePropertyPlaceholderConfigurer) context.getBean("portalPropertyPlaceholder"); assertThat(portalPropertyPlaceholder.getResolvedProps().get("portal.opensocial_engine.root"), is("127.0.0.1:8080")); assertThat(portalPropertyPlaceholder.getResolvedProps().get("dummy.key"), is("Dummy value")); }
