带有eclipse microprofile-config的自定义配置文件

Question

我想在运行时选择.properties文件。 microprofile-config是否可以？因此，我不想使用META-INF / microprofile-config.properties，而是要使用外部文件：

%dw 2.0
output application/json

/**
 * Updates the value of the specified field If the field doesn't exits it will be inserted at the bottom. Use this function with `with`. The with will receive the old value
 */
fun update(objectValue: Object, fieldName: String) = 
    (newValueProvider: (oldValue: Any, index: Number) -> Any) -> do {
        if(objectValue[fieldName]?)
            objectValue mapObject ((value, key, index) -> 
                if(key ~= fieldName)
                    {(key): newValueProvider(value, index)}
                else
                {(key): value}
            )
        else
            objectValue ++ {(fieldName): newValueProvider(null, 0)}
    }

/**
 * Updates the value at the specified index. If the index is bigger than the size it will be appended. Use this function with `with`. The with will receive the old value
 */
fun update(arrayValue: Array, indexToUpdate: Number) = 
    (newValueProvider: (oldValue: Any, index: Number) -> Any) -> do {
        if(arrayValue[indexToUpdate]?)
            arrayValue map ((value, index) -> 
                if(index == indexToUpdate)
                    newValueProvider(value, index)
                else
                    value
            )
        else
            arrayValue << newValueProvider(null, 0)
    }

---
payload update "entities" with (
    $ update 0 with (
        $ update "sourceEnt" with (
            $ update "entity" with (
                $ update "OrgAddr" with (
                        $ map ((item, index) -> item update "MainAddr" with ($ ++ {"StateCode": null}) )
                ) ++ {
                    "Flag" : "yes"
                }
            )
        )
    )
)

我知道，可以编写自定义配置源，但是我想知道是否有内置选项来定义配置文件，从而避免在每个项目中重复代码

Answer 1

The web site告诉我们三个选项：

• System.getProperties()
• System.getenv()
• META-INF/microprofile-config.properties。

除了这些，您还可以注册ConfigSources。

您没有想要的内置选项。
