UTF-8 encoding with Spring Boot 1.1.1
character-encoding, spring-boot, utf-8
Solution
What is wrongly encoded? The request or the response? `server.tomcat.uri-encoding` is switching the URI decoding to `UTF-8` (this is already the case for Jetty).
But that does not do anything for the request body. By default, Spring MVC decodes that with `ISO-8859-1` (that is the default per the servlet spec). You need to specify a body encoding in your request if you want it to be decoded using `UTF-8`. Most users are actually using the `CharacterEncodingFilter` to achieve the same thing (and ensure consistency).
If that fixes your issue, watch out for #1182 that is meant to provide an auto-configuration for that.
Problem
How can I "say" Spring Boot to use the UTF-8 encoding, to show and save German umlauts correctly? We are programming a Java-Webapplication using Sping-Boot 1.1.1 (Release) and as webserver a TomCat7 or Jetty. The database is postgresql or h2 for testing. Edit: I tried it with the properties file (thanks for the answer), but no changes are visible. The database is also UTF-8... Especially the problem comes, when we send a POST-Request to the Webserver. The Spring-Request-Handler gets already the broken encoded values. In the following you can see a part of the code: (It shows a snippet of the Thymeleaf-Template) ``` <form accept-charset="utf-8" method="post"> <div class="row"> <fieldset th:object="${model}"> <!-- CSRF token --> <th:block th:replace="makros :: csrf" /> <div class="col-sm-4 form-group" > <label for="firstname" th:text="#{edit_user.first_name}">Given Name</label> <input class="form-control required" type="text" required="required" id="firstname" name="firstname" th:field="*{firstName}" /> </div> <div class="col-sm-4 form-group"> <label for="firstname" th:text="#{edit_user.last_name}">Family Name</label> <input class="form-control required" type="text" required="required" id="lastname" name="lastname" th:field="*{lastName}" /> </div> </fieldset> </div> </form> ``` And this is the request handler for that: ``` @RequestMapping(method = RequestMethod.POST) public String handleUserUpdate(@ModelAttribute(MODEL) UpdateUserCommand command) { //here we cut the broken encoded values } ``` Greetings Stef
