@Override
 public BoundSql getBoundSql(Object parameterObject) {
   //生成一个动态上下文
   DynamicContext context = new DynamicContext(configuration, parameterObject);
//这里SqlNode.apply只是将${}这种参数替换掉,并没有替换#{}这种参数
   rootSqlNode.apply(context);
//调用SqlSourceBuilder
   SqlSourceBuilder sqlSourceParser = new SqlSourceBuilder(configuration);
   Class<?> parameterType = parameterObject == null ? Object.class : parameterObject.getClass();
//SqlSourceBuilder.parse,注意这里返回的是StaticSqlSource,解析完了就把那些参数都替换成?了,也就是最基本的JDBC的SQL写法
   SqlSource sqlSource = sqlSourceParser.parse(context.getSql(), parameterType, context.getBindings());
//看似是又去递归调用SqlSource.getBoundSql,其实因为是StaticSqlSource,所以没问题,不是递归调用
   BoundSql boundSql = sqlSource.getBoundSql(parameterObject);
   for (Map.Entry<String, Object> entry : context.getBindings().entrySet()) {
     boundSql.setAdditionalParameter(entry.getKey(), entry.getValue());
   }
