Apollo配置参数读取后再做替换

1.先描述业务场景：
在Apollo上做配置，然后读取配置，然后做替换

2.一路坎坷：
2.1.在Apollo上配置，但是vlue包含有占位符“${}”，获取配置报错；

Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'loanName' in value

2.2.去掉$后，不能替换

3.最终代码

    public static final char DEFAULT_ESCAPE = '$';
    /**
     * Constant for the default variable prefix.
     */
    public static final StrMatcher DEFAULT_PREFIX = StrMatcher.stringMatcher("{");
    /**
     * Constant for the default variable suffix.
     */
    public static final StrMatcher DEFAULT_SUFFIX = StrMatcher.stringMatcher("}");

    public static void main(String[] args) {
        Map<Object, Object> paramMap = Maps.newHashMap();
        paramMap.put("username", "张三");
        paramMap.put("loanName", "手机银行");
        StrSubstitutor strSubstitutor = new StrSubstitutor(StrLookup.mapLookup(paramMap), DEFAULT_PREFIX, DEFAULT_SUFFIX, DEFAULT_ESCAPE);
        String message = strSubstitutor.replace("姓名：{username}, 产品名称：'{loanName}");
        System.out.println("message= " + message);

    }
