@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()); } return boundSql; }
