Spring mvc与Apache Tiles 3的集成（使用Java配置）存在问题 [英] Spring mvc integration with Apache Tiles 3 Using Java Configuration has Problems
本文介绍了Spring mvc与Apache Tiles 3的集成（使用Java配置）存在问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
问题是瓦片配置没有每次都应用
。
我已经将Apache tile 3与spring MVC集成在一起。我已经使用了基于注释的spring配置。应用程序中的问题是，切片定义是随机应用的。当我尝试运行该应用程序时，我们配置的tile配置可能会应用，也可能不会应用。
The problem is the that tiles configuration is not getting applied everytime. I have integrated Apache tiles 3 with spring MVC. I have used annotation based configuration of spring. The problem in the application is that the tiles definitions get applied on random basis. When I try to run the application, the tiles configuration that we have configured may or may not get applied.
我正在使用Apache tomcat7。此问题与服务器有关吗？ ？这个问题与配置有关吗？或如果有的话。
I am using Apache tomcat 7. Is this problem related with server? Is this problem related with Configuration? Or If Any.
这是我的代码
MVC配置
Annotation base Java Configuration using Spring
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = { "com.om.*" })
public class MVCConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/layout/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Bean
public TilesViewResolver getTilesViewResolver() {
TilesViewResolver tilesViewResolver = new TilesViewResolver();
tilesViewResolver.setViewClass(TilesView.class);
return tilesViewResolver;
}
@Bean
public TilesConfigurer getTilesConfigurer() {
TilesConfigurer tilesConfigurer = new TilesConfigurer();
tilesConfigurer.setCheckRefresh(true);
tilesConfigurer.setDefinitionsFactoryClass(TilesDefinitionsConfig.class);
// Add apache tiles definitions
TilesDefinitionsConfig.addDefinitions();
return tilesConfigurer;
}
}
MVCInitializer
public class MVCInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { MVCConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
TilesDefinitionsConfig
public final class TilesDefinitionsConfig implements DefinitionsFactory {
private static final Map<String, Definition> tilesDefinitions = new HashMap<String,Definition>();
private static final Attribute BASE_TEMPLATE = new Attribute("/WEB-INF/views/layout/defaultLayout.jsp");
public Definition getDefinition(String name, Request tilesContext) {
System.out.println("3");
return tilesDefinitions.get(name);
}
/**
* @param name <code>Name of the view</code>
* @param title <code>Page title</code>
* @param body <code>Body JSP file path</code>
*
* <code>Adds default layout definitions</code>
*/
private static void addDefaultLayoutDef(String name, String title, String body) {
Map<String, Attribute> attributes = new HashMap<String,Attribute>();
attributes.put("title", new Attribute(title));
attributes.put("header", new Attribute("/WEB-INF/views/layout/header.jsp"));
attributes.put("menu", new Attribute("/WEB-INF/views/layout/menu.jsp"));
attributes.put("body", new Attribute(body));
attributes.put("footer", new Attribute("/WEB-INF/views/layout/footer.jsp"));
tilesDefinitions.put(name, new Definition(name, BASE_TEMPLATE, attributes));
}
/**
* <code>Add Apache tiles definitions</code>
*/
public static void addDefinitions(){
addDefaultLayoutDef("welcome", "welcome", "/WEB-INF/views/layout/welcome.jsp");
addDefaultLayoutDef("personList", "viewPerson", "/WEB-INF/views/layout/personList.jsp");
}
}
控制器
@Controller
public class SpringTilesController {
@RequestMapping(value="welcome")
public ModelAndView index() {
ModelAndView model=new ModelAndView();
System.out.println("In Controller");
model.setViewName("welcome");
return model;
}
@RequestMapping(value="viewPerson")
public ModelAndView viewPersons(Model model) {
Map<String, List<Person>> persons =
new HashMap<String, List<Person>>();
persons.put("persons", Person.createPersons());
return new ModelAndView("personList", persons);
}
}
实体
public class Person {
private String name, email;
private int age;
public Person(String name, String email, int age) {
this.name = name;
this.email = email;
this.age = age;
}
public String getName() {return name;}
public void setName(String name) {this.name = name;}
public String getEmail() {return email;}
public void setEmail(String email) {this.email = email;}
public int getAge() {return age;}
public void setAge(int age) {this.age = age;}
@Override
public String toString()
{
return String.format(
"Person [name = %s, email = %s, age = %d]",
name, email, age);
}
public static List<Person> createPersons() {
List<Person> persons = new ArrayList<Person>();
persons.add(new Person("Tousif", "tousif@mail.com", 32));
persons.add(new Person("Asif", "asif@mail.com", 28));
persons.add(new Person("Ramiz", "ramiz@mail.com", 26));
persons.add(new Person("Rizwan", "rizwan@mail.com", 32));
persons.add(new Person("Amol", "amol@mail.com", 33));
persons.add(new Person("Ramdas", "ramdas@mail.com", 31));
return persons;
}

问题是瓦片配置没有每次都得到应用。
The problem is the that tiles configuration is not getting applied everytime.
推荐答案
在此项目中可以看到没有xml的标题配置开发人员也遇到了类似的问题，磁贴配置无法正常工作。
As you can see in this project Tiles configuration without xml the developer had a similar problem, the tiles configuration isn't working.
他发现，如果您使用相同的文件名来调用视图。jsp，则会出问题。
He found that if you call the view with the same name of the file.jsp, somethings going bad.
public static void addDefinitions(){
addDefaultLayoutDef("welcome", "welcome", "/WEB-INF/views/layout/welcome.jsp");
addDefaultLayoutDef("personList", "viewPerson", "/WEB-INF/views/layout/personList.jsp");
}
尝试对视图和file.jsp使用不同的名称。
尝试
Try to use different name for the view and the file.jsp. Try with
addDefaultLayoutDef("welcome", "Welcome", "/WEB-INF/views/layout/welcome.jsp");
如果其余代码正确，应该可以工作。
Should work if the rest of the code is correct.
