本文介绍了一个基于 Spring MVC 的 Java Web 应用配置示例，包括 pom.xml 中依赖和插件配置、Web 应用初始化配置以及 Spring MVC 的核心配置等。详细展示了如何通过 Maven 管理项目依赖，并提供了 Web 初始配置类和 MVC 配置类的具体实现。

pom.xml的配置

<properties>
        <jdk.version>1.8</jdk.version>
        <spring.version>4.2.2.RELEASE</spring.version>
        <jackson.version>2.6.3</jackson.version>
        <logback.version>1.1.3</logback.version>
        <jcl.slf4j.version>1.7.12</jcl.slf4j.version>

配置启动

public class WebInitialCon extends AbstractDispatcherServletInitializer {

    @Override
    protected WebApplicationContext createServletApplicationContext() {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.scan(ClassUtils.getPackageName(getClass()));
        return context;
    }

    @Override
    protected String[] getServletMappings() {
        // TODO Auto-generated method stub
        return new String[]{"/"};
    }

    @Override
    protected WebApplicationContext createRootApplicationContext() {
        // TODO Auto-generated method stub
        return null;
    }

}

SpringMVC 配置

@EnableWebMvc
@Configuration
@ComponentScan(value="com.lib.web")
public class WebMVCConfiguration extends WebMvcConfigurerAdapter {
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }
    // add the resolver
    @Bean
    public InternalResourceViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/WEB-INF/views/jsps/");
        resolver.setSuffix(".jsp");
        return resolver;
    }
}

配置Controller


 - URL映射
 - 页面跳转和json请求设计以及分离
