Spring Bootで複数のフィルターを設定する

フィルタ内で全て1つでまとめるより

複数に分けたほうが管理し易いよね

やること

  1. Filterをimplementsしたクラスを作成
  2. @Componentsアノテーションは設定しない
  3. WebMvcConfigurerAdapterを継承したクラスで使用するフィルタを設定

フィルタ準備

Sample1Filter.java
package com.example.config.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

public class Sample1Filter implements Filter {
	
	private static final Logger logger = LoggerFactory.getLogger(Sample1Filter.class);

	@Override
	public void init(FilterConfig filterConfig) throws ServletException {
		// 起動時に実行される
		logger.info("Sample1 Filter init");
	}
	 
	@Override
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
			throws IOException, ServletException {
		// リクエスト発行時に実行される
		logger.info("Sample1 Filter doFilter start");
		chain.doFilter(request, response);
		logger.info("Sample1 Filter doFilter end");
	}

	@Override
	public void destroy() {
		// 終了時に実行される
		logger.info("Sample1 Filter destroy");
	}
	
}
Sample2Filter.java
package com.example.config.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

public class Sample2Filter implements Filter {
	
	private static final Logger logger = LoggerFactory.getLogger(Sample2Filter.class);

	@Override
	public void init(FilterConfig filterConfig) throws ServletException {
		// 起動時に実行される
		logger.info("Sample2 Filter init");
	}
	 
	@Override
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
			throws IOException, ServletException {
		// リクエスト発行時に実行される
		logger.info("Sample2 Filter doFilter start");
		chain.doFilter(request, response);
		logger.info("Sample2 Filter doFilter end");
	}

	@Override
	public void destroy() {
		// 終了時に実行される
		logger.info("Sample2 Filter destroy");
	}
	
}

フィルタ設定用クラス

WebConfig.java
package com.example.config;

import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import com.example.config.filter.Sample1Filter;
import com.example.config.filter.Sample2Filter;

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter{
	
	@Bean
	public FilterRegistrationBean sampleFilter1() {		
		FilterRegistrationBean bean = new FilterRegistrationBean();
		bean.setFilter(new Sample1Filter());
		bean.setOrder(2);
		return bean;
	}
	
	@Bean
	public FilterRegistrationBean sampleFilter2() {		
		FilterRegistrationBean bean = new FilterRegistrationBean();
		bean.setFilter(new Sample2Filter());
		bean.setOrder(1);
		return bean;
	}
	
}

こんな感じですかね…

所感

なんとなくDIなどの動きはわかってきたけどBeanの仕組みがいまいちわかってない(´・ω・`)
データの流れを上手く把握しないと記載方法などに影響ができるの少しずつでも理解しておく必要がある。
日本語のマニュアルどっかにないかな〜
