在MyBatis中实现长SQL查询检测可以通过配置插件来实现。具体步骤如下:
public class LongSQLInterceptor implements Interceptor {@Overridepublic Object intercept(Invocation invocation) throws Throwable {StatementHandler statementHandler = (StatementHandler) invocation.getTarget();BoundSql boundSql = statementHandler.getBoundSql();String sql = boundSql.getSql();if (sql.length() > 1000) {throw new RuntimeException("SQL statement is too long");}return invocation.proceed();}@Overridepublic Object plugin(Object target) {return Plugin.wrap(target, this);}@Overridepublic void setProperties(Properties properties) {// 设置拦截器属性}}
<plugins><plugin interceptor="com.example.LongSQLInterceptor"/></plugins>
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);Configuration configuration = sqlSessionFactory.getConfiguration();configuration.addInterceptor(new LongSQLInterceptor());
通过以上步骤,就可以在MyBatis中实现长SQL查询的检测,当SQL语句超过指定长度时会抛出异常。
