[英]Spring boot initialization takes too long to static intialize Spring boot properties with large amount of values
我们在属性文件中有一些静态代码到文本的映射,总代码超过10K,并且我们正在尝试使用静态初始化加载属性文件。 但是初始化应用程序需要2分钟,而无需属性文件,如果我们使用硬编码的hashMap进行初始化,则它非常快。 有没有办法在静态变量中快速加载这些属性?
来自属性文件的几行如下
facetprefix.x4TableMap.cd=CD
facetprefix.x4TableMap.digital=Digital
facetprefix.x4TableMap.lp=LP
@ConfigurationProperties(prefix = "facetprefix")
@PropertySource("classpath:x4-table.properties")
public class X4Table {
private static Map<String, String> x4TableMap;
/**
* initialized map from properties.
* @param x4TableMap map for x4 table code and values
*/
public void setX4TableMap(final Map<String, String> x4TableMap) {
X4Table.x4TableMap = x4TableMap;
}
/**
* @param code Pass in the x0 code, get the full x0: back.
* Return "" if the code does not exist in table.
* @return Pass in the mt code, get the full x0: back.
* Return "" if the code does not exist in table.
*/
public static String getX4(final String code) {
return x4TableMap.get(StringUtils.lowerCase(code));
}
}```
Please let me know if there is a way to Lazy initialize static properties.
