字符串替换

1 准备

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.4</version>
</dependency>

2 实践

这个占位符可以包括unicode字符，也可以包括特殊字符，空格等等

    public static void fillPlaceholder() {
        String template = "Welcome ${中午インターフェ：！:!+-*/ }!  Your last login was ${lastlogin}";
        Map<String, String> data = new HashMap<String, String>();
        data.put("中午インターフェ：！:!+-*/ ", "You");
        data.put("lastlogin", new Date().toString());
        String output = StrSubstitutor.replace(template, data);
        System.out.println(output);
    }

输出：

Welcome You!  Your last login was Thu Mar 01 16:35:25 CST 2018
