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 {
@Override
public 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();
}
@Override
public Object plugin(Object target) {
return Plugin.wrap(target, this);
}
@Override
public 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。
