Spring boot 2.1.3 从 2.0.6 更新导致 BeanDefinitionParsingException 用于 util :map

Question

我在应用程序上下文 xml 中有以下映射 bean 定义，并在 Controller 中使用了导致 spring boot 2.1.3 升级的 BeanDefinitionParsingException 的映射。它在2.0.6 版本 中运行良好。

有人知道如何解决这个问题吗？

在应用程序属性中定义“spring.main.allow-bean-definition-overriding=true”并不能解决问题。

@SpringBootApplication
@PropertySource("classpath:app.properties")
public class Application extends SpringBootServletInitializer {


    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {// NOSONAR
        SpringApplication.run(Application.class, args);
    }

}

@Configuration
public class ApplicationConfig {

    @Configuration
    @ImportResource("classpath*:applicationContext.xml")    
    public static class XmlImportingConfiguration {
    }

}

app.properties
#Spring Boot

server.servlet.context-path=/myapp
spring.application.name=myapp

            <entry key="2880" value="2 days"></entry>
        </util:map>
</beans>

@Controller
@RequestMapping("/")
public class MyController{
    @Resource(name="lookup")
    private Map<String,String> lookup;

}

错误:

我有解决这个问题的方法。基本上将 map 从 applicationContext.xml 移动到应用程序属性并使用 @Value 检索，如下所示。

app.properties
lookup={'60':'Last 1 hour','480':'Last 8 hours','1440':'Last 24 hours','2880':'Last 2 days'}

ApplicationProperties.java
    @Value("#{${lookup}}")
    private Map<String,String> lookupTimeinterval;
