Java Spring无法按配置文件选择自动连线实现
我试图弄清楚如何使用@Autowired注释在Spring中进行模拟实现。我正试图以这样一种方式通过配置文件来推动这一点：Java Spring无法按配置文件选择自动连线实现,java,spring,maven,inversion-of-control,autowired,Java,Spring,Maven,Inversion Of Control,Autowired,我试图弄清楚如何使用@Autowired注释在Spring中进行模拟实现。我正试图以这样一种方式通过配置文件来推动这一点： 有一个默认配置文件，在未定义配置时运行 当指定测试配置文件时，它将自动连接模拟对象，而不是默认实现 在进行这种设置时，我遇到了一个问题，Spring似乎无法区分我的实现之间的差异。我使用的是Tomcat/Jersey/Maven/Spring，没有使用任何xml配置。下面是相关代码（）的运行情况 问题：通过mvn clean tomcat7运行此操作：运行并导航到“/foo
mvn clean tomcat7运行此操作：运行未定义[dkwestbr.spring.autowired.example.IStringGetter]类型的合格bean：预期为单个匹配bean，但找到2:a，bmvn测试时才需要b
我的初始值设定项：
@Override
public void onStartup(ServletContext context) throws ServletException {
AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
appContext.register(AppConfig.class);
context.addListener(new ContextLoaderListener(appContext));
/*
for(String profile: appContext.getEnvironment().getActiveProfiles()) {
System.out.println(String.format("Active profile: %s", profile));
}
*/
Map<String, String> filterParameters = new HashMap<>();
// set filter parameters
filterParameters.put("com.sun.jersey.config.property.packages", "dkwestbr.spring.autowired.example");
filterParameters.put("com.sun.jersey.config.property.JSPTemplatesBasePath", "/WEB-INF/app");
filterParameters.put("com.sun.jersey.config.property.WebPageContentRegex", "/(images|css|jsp)/.*");
SpringServlet servlet = new SpringServlet();
ServletRegistration.Dynamic servletDispatcher = context.addServlet("jersey-servlet", servlet);
servletDispatcher.setInitParameters(filterParameters);
servletDispatcher.setLoadOnStartup(1);
servletDispatcher.addMapping("/*");
}
我的web端点有问题的@Autowired
变量：
@Path("/foo")
@Component
public class WebEndpoint {
@Autowired
private IStringGetter getTheThing;
@GET
@Path("/bar")
@Produces(MediaType.TEXT_HTML)
public String getStuff() {
System.out.println(getTheThing.getItGood());
return String.format("<html><body>Hello - %s</body></html>", getTheThing.getItGood());
}
}
我的第二个实现（我只在运行mvn测试时需要它）：

@ActiveProfiles
注释为
@ActiveProfiles
用于声明哪个bean定义的类级注释
加载用于测试的ApplicationContext时，配置文件应处于活动状态
上课
至于如何设置组件扫描的配置文件，基本上只需将@ActiveProfiles
与@profile
切换，这可以让我的主配置运行（mvn clean tomcat7:run
），但现在测试显示相同的堆栈跟踪，尽管有相同的注释。所以我猜@Profile只在我使用测试概要文件运行时才使类可用。有没有办法让spring说“a没有配置文件，B有测试配置文件，所以选择B，因为测试是当前活动的配置文件”@Dave没有办法说a
没有配置文件。@Profile
注释用于说明此概要文件是否处于活动状态，注册此bean定义，否则跳过它。如果没有注释，则无法停止注册（您可以应用组件扫描
排除过滤器）。实现所需功能的一种方法是使用Profile（“！test”）
注释A
，在这种情况下，只有当test
不是活动的概要文件时，才会注册它。阅读@Profile
的javadoc，它更详细地解释了这一切。Profile（！test）帮了我的忙。像Dave一样，我希望Spring只在“默认”配置文件之上覆盖活动配置文件中的bean。。。
@Component
public class A implements IStringGetter {
@Value("${my.property}")
private String configValue;
@Override
public String getItGood() {
return String.format("I am an A: %s", configValue);
}
}
@Component
@ActiveProfiles("test")
public class B implements IStringGetter {
@Value("${my.property}")
private String configValue;
@Override
public String getItGood() {
return String.format("I am an B: %s", configValue);
}
}
