1. Use spring El instead of OGNL.
2. The bean that accesses the context uses ${@myBean. dosomething ()}
3, Th:field,th:errors,th:errorclass for form processing.
4, to adopt Springtemplateengine.
5. Basic configuration:
<bean id= "Templateresolver"
class= "Org.thymeleaf.templateresolver.ServletContextTemplateResolver" >
<property name= "prefix" value= "/web-inf/templates/"/>
<property name= "suffix" value= ". html"/>
<property name= "Templatemode" value= "HTML5"/>
</bean>
<bean id= "Templateengine"
class= "Org.thymeleaf.spring3.SpringTemplateEngine" >
<property name= "Templateresolver" ref= "Templateresolver"/>
</bean>
<bean class= "Org.thymeleaf.spring3.view.ThymeleafViewResolver" >
<property name= "Templateengine" ref= "Templateengine"/>
<property name= "Order" value= "1"/>
<property name= "Viewnames" value= "*.html,*.xhtml"/>
</bean>
6, methods that are annotated by @modelattribute are executed before each method of the controller is executed, and if the method of the @modelattribute annotation has a return value, the Property object that holds the implied name in the model. Return account, for example, is equivalent to Model.addattribute ("account", account), if @modelattribute (value= "aname") annotation method, Indicates that the value of the Aname property is increased in the model. @ModelAttribute Note the parameters of a method are taken from the model or from the form form or URL.
7, @RequestMapping ("/hello") public void Novoid () {}, returns the view as a prefix +/hello+ suffix, when the method returns a map, Modelmap and so on are equivalent to Request.setattribute ().
8, <td th:text= "${{sb.dateplanted}" >13/01/2011</td> double brackets denote automatic use of transformations, often used in format conversions.
9, <td th:text= "${#strings. Arrayjoin (#messages. arraymsg (#strings. Arrayprepend (Sb.features, ' Seedstarter.feature. ')}, ', ')} ">electric heating, turf</td> First prefix the array feathers and then use the messages translation to internationalize, Eventually combined into a string.
10, specify command object with Th:object, for example: <form action= "#" th:action= "@{/save}" th:object= "${person}" method= "POST" , two-point limit, the first object can only be the model of the direct attribute, cannot make ${person.baseinfo}, second, th:object child tags can no longer use Th:object. Inputfield use: <input type= "text" th:field= "*{dateplanted}"/>.
12, checkbox label:
<div>
<label th:for= "${#ids. Next (' Covered ')}" th:text= "#{seedstarter.covered}" >Covered</label>
<input type= "checkbox" th:field= "*{covered}"/>
</div>
CheckBox array:
<ul>
<li th:each= "feat: ${allfeatures}" >
<input type= "checkbox" th:field= "*{features}" th:value= "${feat}"/>
<label th:for= "${#ids. Prev (' Features ')} ' th:text= ' #{${' seedstarter.feature. ' + feat} ' >Heating</label>
</li>
</ul>
13, Radios:
<ul>
<li th:each= "ty: ${alltypes}" >
<input type= "Radio" th:field= "*{type}" th:value= "${ty}"/>
<label th:for= "${#ids. Prev (' type ')}" th:text= "#{${' seedstarter.type. ' + ty}}" >Wireframe</label>
</li>
</ul>
14, DropDownList or select.
<select th:field= "*{type}" >
<option th:each= "type: ${alltypes}"
Th:value= "${type}"
th:text= "#{${' seedstarter.type. ' + type} ' >Wireframe</option>
</select>
15, preprocessing: <select th:field= "*{rows[__${rowstat.index}__].variety}" > instead of using <select th:field= "*{rows[ Rowstat.index].variety} ", because spring El does not evaluate variables or expressions in the array index.
16, Error display: <input type= "text" th:field= "*{dateplanted}" th:class= "${#fields. HasErrors (' dateplanted ')}? Fielderror "/>
<ul>
<li th:each= "ERR: ${#fields. Errors (' dateplanted ')}" th:text= "${err}"/>
</ul>
<input type= "text" th:field= "*{dateplanted}"/>
<p th:if= "${#fields. HasErrors (' dateplanted ')}" th:errors= "*{dateplanted}" >incorrect date</p>
<input type= "text" th:field= "*{dateplanted}" class= "small" th:errorclass= "Fielderror"/>
<ul th:if= "${#fields. HasErrors (' * ')}" >
<li th:each= "ERR: ${#fields. Errors (' * ')}" th:text= "${err}" >input is incorrect</li>
</ul> Global Error:
<ul th:if= "${#fields. HasErrors (' Global ')}" >
<li th:each= "ERR: ${#fields. Errors (' Global ')}" th:text= "${err}" >input is incorrect</li>
</ul> display errors outside the form:
<div th:errors= "${myform}" >...</div>
<div th:errors= "${myform.date}" >...</div>
<div th:errors= "${myform.*}" >...</div>
<div th:if= "${#fields. HasErrors (' ${myform} ')}" >...</div>
<div th:if= "${#fields. HasErrors (' ${myform.date} ')}" >...</div>
<div th:if= "${#fields. HasErrors (' ${myform.*} ')}" >...</div>
<form th:object= "${myform}" >
...
</FORM>17, using the function class conversion: #conversions. CONVERT (Object,class), #conversions. CONVERT (object,string)
18, the fragment of the rendering template, commonly used in Ajax, return a part of the text to replace the use.
To specify a fragment in Viewbean:
<bean name= "Content-part" class= "Org.thymeleaf.spring3.view.ThymeleafView" >
<property name= "templatename" value= "index"/>
<property name= "Fragmentspec" >
<bean class= "Org.thymeleaf.standard.fragment.StandardDOMSelectorFragmentSpec"
c:selectorexpression= "Content"/>
</property>
</bean>
@RequestMapping ("/showcontentpart")
Public String Showcontentpart () {
...
return "Content-part";//returns the bean name defined above.
}
c:selectorexpression= "Content": you need to add th:fragment to the content node. C:selectorexpression= "#content": completely based on the HTML DOM selector, without th:fragment.
Specify the fragment in the controller:
@RequestMapping ("/showcontentpart")
Public String Showcontentpart () {
...
Return "Index:: Content";
The difference between "index:: Content" and "Index:: #content" is the same.
You can also return a fragment with parameters:
@RequestMapping ("/showcontentpart")
Public String Showcontentpart () {
...
Return "index:: #content (' myvalue ')";
}
SPRING + THYMELEAF Configuration
