只需更改导入顺序即可。类似于：

<context:property-placeholder file-encoding="UTF-8"
                            location="${YOUR_CUSTOM_PATH}/global.properties ,
                                      ${YOUR_CUSTOM_PATH}/local.properties" ignore-unresolvable="true"/>

或

@PropertySource(value = {"classpath:global.properties" , "local.properties"},ignoreResourceNotFound = true)

在这种情况下，local.properties重写global.properties的属性
