springboot 的一般配置

import javax.servlet.Filter;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.MultipartAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.filter.HttpPutFormContentFilter;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;

//exclude表示自动配置时不包括Multipart配置
@EnableAutoConfiguration(exclude = {MultipartAutoConfiguration.class})
@SpringBootApplication
@EnableTransactionManagement
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    @Bean
    public Filter initializeHttpPutHandler() {
        return new HttpPutFormContentFilter();
    }

    @Bean
    public CharacterEncodingFilter initializeCharacterEncodingFilter() {
        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        filter.setForceEncoding(true);
        return filter;
    }

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setDefaultEncoding("UTF-8");
        resolver.setResolveLazily(true);// resolveLazily属性启用是为了推迟文件解析
        resolver.setMaxInMemorySize(40960);
        resolver.setMaxUploadSize(50 * 1024 * 1024);// 上传文件大小 50M 50*1024*1024
        return resolver;
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
