tomcat的在idea中亂碼問題
設置tocmat插件的 VM參數
2.配置
2.1啓動配置
方式一 推薦
web項目中啓動
public class AnnotationConfigDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
/**
* rootConfig
* createRootApplicationContext() root application context
* @return
*/
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{RootConfig.class};
}
/**
* web 應用填寫這個配置就可以
* createServletApplicationContext() Servlet application context
* @return
*/
@Override
protected Class<?>[] getServletConfigClasses() {
// return new Class[0];
return new Class<?>[]{RootConfig.class};
}
/** 配置spring mapping訪問 */
@Override
protected String[] getServletMappings() {
// return new String[0];
// return new String[]{"/"};
return new String[]{"*.do"};
}
/**
* 註冊 filter
*/
@Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
return new Filter[]{characterEncodingFilter};
}
}
方式二
實現 WebApplicationInitializer 接口 MyWebAppInitializer
public class MyWebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
ServletContext container = servletContext;
// Create the 'root' Spring application context
AnnotationConfigWebApplicationContext rootContext =
new AnnotationConfigWebApplicationContext();
rootContext.register(AppConfig.class);
// Manage the lifecycle of the root application context
container.addListener(new ContextLoaderListener(rootContext));
// Create the dispatcher servlet's Spring application context
AnnotationConfigWebApplicationContext dispatcherContext =
new AnnotationConfigWebApplicationContext();
dispatcherContext.register(DispatcherConfig.class);
// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher =
container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
2.2 spring rootConfig配置
RootConfig
@EnableWebMvc
@Configuration
@ComponentScan(basePackages={"com.lwp.**.controller","com.lwp"})
public class RootConfig {
}
2.3 springmvc配置
SpringMvcConfig
SpringMvcConfig 繼承 WebMvcConfigurationSupport 實現設置配置
@Configuration
public class SpringMvcConfig extends WebMvcConfigurationSupport {
/**
* 配置springmvc視圖
* @return
*/
@Bean
public ViewResolver viewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
// resolver.setPrefix("/pages/");
// resolver.setPrefix("/WEB-INF/pages/");
resolver.setPrefix("/");
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
// 文件上傳
/* public CommonsMultipartResolver commonsMultipartResolver() {
CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
// 默認 -1 indicates no limit
// 100M = 104857600
// commonsMultipartResolver.setMaxUploadSize(104_857_600);
retrn commonsMultipartResolver;
}*/
@Bean
public StringHttpMessageConverter stringHttpMessageConverter() {
StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter();
List<MediaType> supportedMediaTypes = new ArrayList<>();
supportedMediaTypes.add(MediaType.TEXT_HTML);
supportedMediaTypes.add(MediaType.TEXT_PLAIN);
stringHttpMessageConverter.setSupportedMediaTypes(supportedMediaTypes);
return stringHttpMessageConverter;
}
@Override
public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
/*FastJsonHttpMessageConverter fjc = new FastJsonHttpMessageConverter();
FastJsonConfig fj = new FastJsonConfig();
fj.setSerializerFeatures(SerializerFeature.DisableCircularReferenceDetect);
fjc.setFastJsonConfig(fj);
converters.add(fjc);*/
// 新增自定義消息轉換
StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter();
List<MediaType> supportedMediaTypes = new ArrayList<>();
// MediaType.valueOf("text/plain;charset=UTF-8")
// MediaType.valueOf("text/html;charset=UTF-8")
supportedMediaTypes.add(MediaType.TEXT_HTML);
supportedMediaTypes.add(MediaType.TEXT_PLAIN);
stringHttpMessageConverter.setDefaultCharset(Charset.forName("UTF-8"));
stringHttpMessageConverter.setSupportedMediaTypes(supportedMediaTypes);
converters.set(1, stringHttpMessageConverter);
}
}
自定義消息轉換器
默認的轉換器
其他
執行順序由先到後
- WebApplicationInitializer
- ApplicationContextAware
1. WebApplicationInitializer
public class MyWebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
System.out.println("WebApplicationInitializer ...");
/*ServletContext container = servletContext;
// Create the 'root' Spring application context
AnnotationConfigWebApplicationContext rootContext =
new AnnotationConfigWebApplicationContext();
rootContext.register(AppConfig.class);
// Manage the lifecycle of the root application context
container.addListener(new ContextLoaderListener(rootContext));
// Create the dispatcher servlet's Spring application context
AnnotationConfigWebApplicationContext dispatcherContext =
new AnnotationConfigWebApplicationContext();
dispatcherContext.register(DispatcherConfig.class);
// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher =
container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");*/
}
}
2. ApplicationContextAware
@Component
public class MyWebApplicationAware implements ApplicationContextAware {
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
System.out.println(applicationContext);
System.out.println(99999999);
}
}
