Question

我使用spring 3.0.6-RELEASE用于基于Web应用程序的基本形式，并在使用PropertyPlaceHolderConfigurer启动时遇到以下错误。不知道是什么导致了这一点，因为注入属性pre-mvc3是通过bean完成的，现在使用注释，它至少在文档/其他帖子中非常简单。

然而，tomcat服务器启动期间的异常会引发org.springframework.core.ConstantException：在类[org.springframework.beans.factory.config.PropertyPlaceholderConfigurer]中找不到字段'SYSTEM_PROPERTIES_MODE_ENVIRONMENT'

这是我在spring-servlet.xml中的内容

<context:property-placeholder location="/WEB-INF/classes/spring.properties"/>

和我的控制器类

@Controller
@RequestMapping("/home")

public class HomeController {

    // @Resource(name="broomManager")
    @Autowired
    private broomManager broomManager;
    private @Value("${spring.broom.maxFileSize}") String inMemoryMaxFileSize;
    private @Value("${spring.broom.fileDestination}") String destFilePath;

...

spring.properties

broom.maxFileSize=100000
broom.fileDestination=/Users/foobar/broom/files/

启动时出现异常

可能会发生以下情况：

您的Spring配置文件指向3.1架构。
您正在使用3.0.6 JAR。

他们需要匹配。

Field＆＃39; SYSTEM_PROPERTIES_MODE_ENVIRONMENT＆＃39;之间的关系是什么？和PropertyPlaceHolderConfigurer？
