MyBatis Profiler

MyBatisProfiler is a Plugin for MyBatis that keeps track of executed mapped statements.

Example output:

/app/secure/home/index.jsf
+------------------------------------------+-------+---------------+---------------+
| MappedStatement                          | Times | Min. Response | Max. Response |
+-------------------- ---------------------+-------+---------------+---------------+
| org.raupach.data.FooMapper.selectByValue |      7|              1|              4|
| org.raupach.data.FooMapper.selectOne     |      1|              6|              6|
+------------------------------------------+-------+---------------+---------------+

Installation

First add mybatis-profiler-0.1.jar to your classpath.

You can start and stop profiling programmatically or with a servlet filter.

<filter-mapping>
