我有一个Spring Java配置对象,它加载我的属性,但不会覆盖MessageSource令牌。
@Configuration
@SuppressWarnings("unused")
public class PropertyConfiguration {
public static final String PROPERTY_OVERRIDE_URL = "d2.config.location";
@Bean
public UrlResource propertyOverrideUrl() {
String propertyOverrideUrl = System.getProperty(PROPERTY_OVERRIDE_URL);
UrlResource overrideUrl = null;
// just add a bogus url as to not get a malformed URL
try{
overrideUrl = new UrlResource(
(propertyOverrideUrl == null || "".equals(propertyOverrideUrl)? "file:///FILENOTFOUND" : propertyOverrideUrl)
);
} catch (MalformedURLException e){
// Set the URL to a dummy value so it will not break.
try{
overrideUrl = new UrlResource("file:///FILENOTFOUND");
} catch (MalformedURLException me){
// this is a valid URL, but will not be found at runtime.
}
}
return overrideUrl;
}
@Bean
@DependsOn("propertyOverrideUrl")
@Lazy(false)
public ContextAwarePropertyPlaceholderConfigurer propertyPlaceholderConfigurer()
throws IOException{
return new ContextAwarePropertyPlaceholderConfigurer(){{
setLocations(new Resource[]{
new ClassPathResource("application_prompts.properties"),
new ClassPathResource("application_webservice.properties"),
new ClassPathResource("application_externalApps.properties"),
new ClassPathResource("application_log4j.properties"),
new ClassPathResource("application_fileupload.properties"),
//Must be last to override all other resources
propertyOverrideUrl()
});
setIgnoreResourceNotFound(true);
}};
}
当我在javaconfig属性上运行单元测试时,它很好:
@Test
public void testOverrides__Found() throws Exception {
setOverrideUrlSystemProperty("/target/test/resources/override-test.properties");
context = SpringContextConfigurationTestHelper.createContext();
context.refresh();
String recordedPaymentConfirmationPath =
(String)context.getBean("recordedPaymentConfirmationPath");
assertThat(recordedPaymentConfirmationPath, is("test/dir/recordings/"));
String promptServerUrl =
(String)context.getBean("promptServerUrl");
assertThat(promptServerUrl, is("http://test.url.com"));
}
但是当我尝试使用MessageSource的值时,它仍然具有旧值:
@Test
public void testOverrides__XYZ() throws Exception {
setOverrideUrlSystemProperty("/target/test/resources/override-test.properties");
context = SpringContextConfigurationTestHelper.createContext();
context.refresh();
String promptServerUrl = (String)context.getMessage("uivr.prompt.server.url",
new Object[] {}, Locale.US);
assertThat(promptServerUrl, is("http://test.url.com"));
}
输出:
[junit] Testcase: testOverrides__XYZ took 0.984 sec
[junit] FAILED
[junit]
[junit] Expected: is "http://test.url.com"
[junit] got: "http://24.40.46.66:9010/agent-ivr-prompts/"
[junit]
[junit] junit.framework.AssertionFailedError:

[junit]
[junit] at com.comcast.ivr.agent.configuration.PropertyOverrideConfigurationTest.testOverrides__XYZ(PropertyOverrideConfigurationTest.java:114)
有人可以帮我找到覆盖MessageSource的方法,因为这是我们的力度模板中使用的方法:
#set($baseUrl = "#springMessage('uivr.prompt.server.url')")
我添加了一些日志记录:
@Override
protected void loadProperties(Properties props) throws IOException {
super.loadProperties(props);
super.mergeProperties();
if(logger.isDebugEnabled()){
System.out.println("--------------------");
for (Map.Entry entry : props.entrySet()) {
System.out.println(entry.getKey() + ":" + entry.getValue());
logger.info(entry.getKey() + ":" + entry.getValue());
}
System.out.println("--------------------");
}
}
并按预期打印值。
...
[junit] uivr.prompt.server.url:http://test.url.com

答案 0 :(得分:0)
关于propertyPlaceholderConfigurer()
@Bean
方法中使用的注释的几个附注:
Lazy(false)
是不必要的,因为它已经是默认值。你可以省略这个。@DependsOn("propertyOverrideUrl")
是不必要的,因为已经通过在propertyOverrideUrl()
propertyPlaceholderConfigurer()
来确定依赖关系
关于你的实际问题,回答有点困难因为我不确定ContextAwareProperyPlaceholderConfigurer
是做什么的(我假设它是一个自定义组件,因为它不是核心Spring框架的一部分)。
PropertyPlaceholderConfigurer
(PPC)和朋友通过后处理bean定义来替换${...}
占位符,但不以任何方式与MessageSource
个对象交互。所以你所描述的行为,我相信,正如预期的那样:你会在询问bean时看到'正确'的URL(因为它已被你的PPC后处理),但是在查询消息时你会看到'错误的'url来源(因为它与PPC后处理完全无关)。
希望这有帮助。
