SSM注解配置 往Spring Boot 过渡

AppConfig.java

@Configuration@EnableAspectJAutoProxy@ComponentScan(basePackages = {xxx}, excludeFilters = @Filter(Controller.class))public class AppConfig {}

WebMvcConfig.java

@Configuration@ComponentScan(basePackages = {xxx})public class WebMvcConfig extends WebMvcConfigurationSupport {

MybatisConfig.java

@Configuration@PropertySource("classpath:jdbc.properties")@MapperScan("xxx")@ImportResource("classpath:transaction.xml")public class MybatisConfig {}

MyWebAppInitializer.java

public class MyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {    @Override    protected Class<?>[] getRootConfigClasses() {        return new Class[]{AppConfig.class, MybatisConfig.class};    }    @Override    protected Class<?>[] getServletConfigClasses() {        return new Class[]{WebMvcConfig.class};    }    @Override    protected String[] getServletMappings() {        return new String[]{"/"};    }

SpringMVC全注解配置时，定制Jackson配置，不生效。原因是我开启@EnableWebMvc 然后又继承了WebMvcConfigurationSupport。查看@EnableWebMvc，发现其注解解析的类为DelegatingWebMvcConfiguration而其又是继承WebMvcConfigurationSupport。
