This example demonstrates how to use XSLT as the view technology in a Spring MVC application
Example
Java Config class
@EnableWebMvc
@Configuration
@ComponentScan
public class MyWebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver xsltViewResolver() {
XsltViewResolver viewResolver = new XsltViewResolver();
viewResolver.setPrefix("/WEB-INF/xsl/");
viewResolver.setSuffix(".xslt");
return viewResolver;
}
}
Writing a Spring Controller
@Controller
@RequestMapping("/")
public class MyController {
@Autowired
private ResourceLoader resourceLoader;
@GetMapping("/")
public String javaTutorial(Model model) {
Resource resource = resourceLoader.getResource("classpath:employees.xml");
model.addAttribute("employees", resource);
return "employees";
}
}
In this example, we are loading an XML file from classpath. and adding the resource to Model. The XML data will be transformed per target XSLT file.
Note that, we can alternatively prepare XML content as DOM document and add it to the model:
Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Element root = document.createElement("employees");
.............
model.addAttribute("employees", root);
XML Resource
src/main/resources/employees.xml<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<employees>
<employee>
<id>100</id>
<name>Sara</name>
<dept>Admin</dept>
</employee>
<employee>
<id>200</id>
<name>Mike</name>
<dept>Account</dept>
</employee>
<employee>
<id>300</id>
<name>Joe</name>
<dept>IT</dept>
</employee>
<employee>
<id>400</id>
<name>Cindy</name>
<dept>IT</dept>
</employee>
</employees>
XSLT file
src/main/webapp/WEB-INF/xsl/employees.xslt<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" indent="yes"/>
<xsl:template match="/">
<html>
<head>
<style>
table.emp {
border-collapse: collapse;
}
table.emp, table.emp th, table.emp td {
border: 1px solid gray;
}
</style>
</head>
<body>
<div align="center">
<xsl:apply-templates/>
</div>
</body>
</html>
</xsl:template>
<xsl:template match="employees">
<table class="emp" style="width:100%;">
<tr bgcolor="#eee">
<th>Id</th>
<th>Name</th>
<th>Department</th>
</tr>
<xsl:for-each select="employee">
<tr>
<td>
<xsl:value-of select="id"/>
</td>
<td>
<xsl:value-of select="name"/>
</td>
<td>
<xsl:value-of select="dept"/>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
Output
Output HTML source:
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style>
table.emp {
border-collapse: collapse;
}
table.emp, table.emp th, table.emp td {
border: 1px solid gray;
}
</style>
</head>
<body>
<div align="center">
<table class="emp" style="width:100%;">
<tr bgcolor="#eee">
<th>Id</th><th>Name</th><th>Department</th>
</tr>
<tr>
<td>100</td><td>Sara</td><td>Admin</td>
</tr>
<tr>
<td>200</td><td>Mike</td><td>Account</td>
</tr>
<tr>
<td>300</td><td>Joe</td><td>IT</td>
</tr>
<tr>
<td>400</td><td>Cindy</td><td>IT</td>
</tr>
</table>
</div>
</body>
</html>
