Spring4 + Tiles3 web.xml零配置

1、

SpitterWebInitializer.java

package spittr.config;

import javax.servlet.Filter;
import org.springframework.web.filter.CharacterEncodingFilter;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import spittr.web.WebConfig;


public class SpitterWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
  
    //得到中间层(service、dao、aop、po等)的配置
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { RootConfig.class };
    }
  
    //得到controler和ViewResolver的配置
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }
  
    //标识哪些url要经过这个DisptacherServlet处理
    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
    
    
    /**
     * 注册过滤器，映射路径与DispatcherServlet一致，路径不一致的过滤器需要注册到另外的WebApplicationInitializer中
     * encoding 用来设置编码格式
     * forceEncoding 用来设置是否理会 request.getCharacterEncoding()方法，设置为true则强制覆盖之前的编码格式
     *               只要你设置了foreEncoding=true，则在代码中设置编码格式没用
     */
    @Override  
    protected Filter[] getServletFilters() {  
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();  
        characterEncodingFilter.setEncoding("UTF-8");  
        characterEncodingFilter.setForceEncoding(true);
        return new Filter[] {characterEncodingFilter};  
    }
    

}

2、

RootConfig.java

package spittr.config;


import java.util.regex.Pattern;


import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.Import;
import org.springframework.core.type.filter.RegexPatternTypeFilter;


import spittr.config.RootConfig.WebPackage;


@Configuration
@Import(DataConfig.class)
@ComponentScan(basePackages={"spittr"}, 
    excludeFilters={
        @Filter(type=FilterType.CUSTOM, value=WebPackage.class)
    })
public class RootConfig {
  public static class WebPackage extends RegexPatternTypeFilter {
    public WebPackage() {
      super(Pattern.compile("spittr\\.web"));
    }    
  }
}

3、WEB配置

WebConfig.java

package spittr.web;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.tiles3.TilesConfigurer;
import org.springframework.web.servlet.view.tiles3.TilesViewResolver;


@Configuration
@EnableWebMvc
@ComponentScan("spittr.web")
public class WebConfig extends WebMvcConfigurerAdapter {


  @Override
  public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
  }
  
  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    // TODO Auto-generated method stub
    super.addResourceHandlers(registry);
  }


  
  // Tiles
  @Bean
  public TilesConfigurer tilesConfigurer() {
    TilesConfigurer tiles = new TilesConfigurer();
    tiles.setDefinitions(new String[] {
        "/WEB-INF/layout/tiles.xml",
        "/WEB-INF/views/**/tiles.xml"
    });
    tiles.setCheckRefresh(true);
    return tiles;
  }
  
  @Bean
  public ViewResolver viewResolver() {
    return new TilesViewResolver();
  }
  
}

4、配置一个H2嵌入式数据库，测试时十分有用

DataConfig.java

package spittr.config;


import javax.sql.DataSource;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcOperations;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType;


@Configuration
public class DataConfig {


  @Bean
  public DataSource dataSource() {
    return new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.H2)
            .addScript("schema.sql")
            .build();
  }
  
  @Bean
  public JdbcOperations jdbcTemplate(DataSource dataSource) {
    return new JdbcTemplate(dataSource);
  }


}

5、tiles配置文件  新配置方式 详见另一篇文章 Tiles框架教程 简单规则 解决匹配问题

tiles.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
  "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
  "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
<tiles-definitions>


    <definition name="base" template="/WEB-INF/layout/page.jsp">
        <put-attribute name="header" value="/WEB-INF/layout/header.jsp" />
        <put-attribute name="footer" value="/WEB-INF/layout/footer.jsp" />
    </definition>


    <definition name="controller" extends="base">
        <put-attribute name="body" expression="/WEB-INF/views${view}.jsp" />
    </definition>


</tiles-definitions>
