Java 'server.servlet.session.persistent'的默认值`

我如何从Spring Boot文档中看到

server.servlet.session.persistent

选项的默认值是

false

，但在我的应用程序中它是

true

，这很奇怪，因为我没有显式修改它。我想SpringSecurity、SpringSession或SpringRedis集成会将它变成

true

。也许有人知道这种行为的根源

另外，我使用弹簧靴2.1.5

默认情况下，属性

server.servlet.session.persistent

为

false

。但是，它被SpringDevTools覆盖，它将它设置为

true

（我认为是由于它的重启/热重新加载功能）

如果不希望会话持久性，请直接在

应用程序.properties

文件或与开发配置文件对应的属性文件中禁用它

您可以查看上的源代码，Spring开发工具在Spring环境中设置了多个属性：

static {
    Map<String, Object> properties = new HashMap<>();
    properties.put("spring.thymeleaf.cache", "false");
    properties.put("spring.freemarker.cache", "false");
    properties.put("spring.groovy.template.cache", "false");
    properties.put("spring.mustache.cache", "false");
    properties.put("server.servlet.session.persistent", "true");
    properties.put("spring.h2.console.enabled", "true");
    properties.put("spring.resources.cache.period", "0");
    properties.put("spring.resources.chain.cache", "false");
    properties.put("spring.template.provider.cache", "false");
    properties.put("spring.mvc.log-resolved-exception", "true");
    properties.put("server.error.include-stacktrace", "ALWAYS");
    properties.put("server.servlet.jsp.init-parameters.development", "true");
    properties.put("spring.reactor.debug", "true");
    PROPERTIES = Collections.unmodifiableMap(properties);
}

静态{
映射属性=新的HashMap（）；
properties.put（“spring.thymeleaf.cache”、“false”）；
properties.put（“spring.freemarker.cache”、“false”）；
properties.put（“spring.groovy.template.cache”、“false”）；
properties.put（“spring.mustache.cache”、“false”）；
properties.put（“server.servlet.session.persistent”、“true”）；
properties.put（“spring.h2.console.enabled”，“true”）；
properties.put（“spring.resources.cache.period”，“0”）；
properties.put（“spring.resources.chain.cache”，“false”）；
properties.put（“spring.template.provider.cache”，“false”）；
properties.put（“spring.mvc.log解析异常”，“true”）；
properties.put（“server.error.include stacktrace”、“始终”）；
properties.put（“server.servlet.jsp.init parameters.development”、“true”）；
properties.put（“spring.reactor.debug”、“true”）；
属性=集合。不可修改的映射（属性）；
}
