As long as request processing does not cause an unhandled exception, the `print()` method |

print all the available result data to `System.out`. |
|
|
|
will print all the available result data to `System.out`. Spring Framework 4.2 introduces |
|
|
|
|
|
|
|
a new `log()` method and two additional variants of the `print()` method: one that accepts |
|
|
|
|
|
|
|
an `OutputStream` and one that accepts a `Writer`. For example, invoking |
|
|
|
|
|
|
|
`print(System.err)` will print the result data to `System.err`; while invoking |
|
|
|
|
|
|
|
`print(myWriter)` will print the result data to a custom writer. If you would like to |
|
|
|
|
|
|
|
have the result data _logged_ instead of printed, simply invoke the `log()` method which |
|
|
|
|
|
|
|
will log the result data as a single `DEBUG` message under the |
|
|
|
|
|
|
|
`org.springframework.test.web.servlet.result` logging category. |
