Question

我在应用程序上下文xml中具有以下映射bean定义，并在控制器中使用了映射，这导致BeanDefinitionParsingException导致 spring boot 2.1.3升级。在 2.0.6版本中可以正常使用。

有人知道如何解决此问题吗？

在应用程序属性中定义“ spring.main.allow-bean-definition-overriding=true”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.contextPath=/myapp
server.servlet.context-path=/myapp
spring.application.name=myapp
server.tomcat.max-threads=200
server.port=901

            <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：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：名称为“ lookup”的无效bean定义在null中定义：无法注册bean定义[Generic bean：class [org.springframework.beans.factory.config.MapFactoryBean]; scope =; abstract = false; lazyInit = false; autowireMode = 0; dependencyCheck = 0; autowireCandidate = true; primary = false; factoryBeanName = null; factoryMethodName = null; initMethodName = null; destroyMethodName = null] 对于bean'lookup'：已经有[Generic bean：class [org.springframework.beans.factory.config.MapFactoryBean]; scope =; abstract = false; lazyInit = false; autowireMode = 0; dependencyCheck = 0; autowireCandidate = true; primary = false; factoryBeanName = null; factoryMethodName = null; initMethodName = null; destroyMethodName = null] 绑定。

Answer 1

我有解决此问题的方法。基本上将地图从applicationContext.xml移动到应用程序属性，并使用@Value进行检索，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;

Answer 2

这可能不是您要查找的内容，但是为什么不用Java Config替换XML。您不应该启用bean覆盖，因为它会使调试Spring IoC启动问题非常非常困难。

@Configuration
public class ApplicationConfig {

    @Bean
    public Map<String, String> lookup() {
      return Map.of(
            "60", "1 hour", 
            "480", "8 hour", 
            "1440", "24 hours", 
            "2880", "2 days"
      );
    }

}

Answer 3

如果您不想使用“ application.properties”文件，也可以使用“ yaml”文件。

Yaml支持属性中的键值。

application.yaml

myVales:
  60: "1 hour" 
  480: "8 hour" 
  1440: "24 hours" 
  2880: "2 days"

MyConfig.class

@Configuration
@ConfigurationProperties
public class MyConfig {

    private Map<String, String> myValues;

    //getters

}

从2.0.6更新的Spring Boot 2.1.3导致util：map的BeanDefinitionParsingException
