As user482745 suggests in the comments (now deleted), the string concatenation I previously suggested <form th:action=”@{/mycontroller/} + ${type}”> will fail in some web contexts. Thymeleaf uses LinkExpression that resolves the @{..} expression. Internally, this uses HttpServletResponse#encodeURL(String). Its javadoc states For robust session tracking, all URLs emitted by a servlet should be run through this method. … Read more
The shortest way is using ‘?’ operator. If you have User entity with embedded Address entity in order to access fields of Address entity and print them if address is not null, otherwise here will be an empty column: <td th:text=”${user?.address?.city}”></td>
Thymeleaf th:each allows you to declare an iteration status variable <span th:each=”task,iter : ${foo.tasks}”> Then in the loop you can refer to iter.index and iter.size. See Tutorial: Using Thymeleaf – 6.2 Keeping iteration status.
Check for the name of the templates folder. it should be templates not template(without s).
This is how I populate the drop down list.I think it may help to you get some idea about it. Controller List<Operator> operators = operatorService.getAllOperaors() model.addAttribute(“operators”, operators); Model @Entity @Table(name = “operator”) public class Operator { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = “id”) @JsonIgnore private Long id; @NotBlank(message=”operator Name cannot be empty”) @Column(name = “operator_name”, … Read more
You can find an example in http://www.thymeleaf.org/doc/tutorials/2.1/thymeleafspring.html#creating-a-form. As the tutorial suggests, you need to use th:object, th:action and th:field to create a form in Thymeleaf. It looks like this: Controller: @RequestMapping(value = “/showForm”, method=RequestMethod.GET) public String showForm(Model model) { Foo foo = new Foo(); foo.setBar(“bar”); model.addAttribute(“foo”, foo); … } @RequestMapping(value = “/processForm”, method=RequestMethod.POST) public String … Read more
In Spring Boot 1.4.x you can add a custom error page: If you want to display a custom HTML error page for a given status code, you add a file to an /error folder. Error pages can either be static HTML (i.e. added under any of the static resource folders) or built using templates. The … Read more
According to the official documentation: <script th:inline=”javascript”> /*<![CDATA[*/ var message = /*[[${message}]]*/ ‘default’; console.log(message); /*]]>*/ </script>
You can use th:utext attribute that stands for unescaped text (see documentation). Use this with caution and avoid user input in th:utext as it can cause security problems. <div th:remove=”tag” th:utext=”${n}”></div>
Thymeleaf has an equivalent to <c:choose> and <c:when>: the th:switch and th:case attributes introduced in Thymeleaf 2.0. They work as you’d expect, using * for the default case: <div th:switch=”${user.role}”> <p th:case=”‘admin'”>User is an administrator</p> <p th:case=”#{roles.manager}”>User is a manager</p> <p th:case=”*”>User is some other thing</p> </div> See this for a quick explanation of syntax … Read more
