1、XML 中使用 \#\{\}，Java 代码中传入 "%参数值%"

Java:
        list< User> users = mapper.select(Collections.singleMap("name", "%constxiong%"));
     
    XML:
        < select id=”select” resultMap="User" parameterType="String">
          select * from user where name like #{name}
        < /select>

2、XML 中使用 $\{\}，Java 代码中传入

Java:
        list< User> users = mapper.select(Collections.singleMap("name", "constxiong"));
     
    XML:
        < select id=”select” resultMap="User" parameterType="String">
            select * from user where name like '%${name}%'
        < /select>
