要让那些黄色配置生效,要自己写一个配置类。
https://blog.csdn.net/justlpf/article/details/80728529详细解释
代码:
application.yml:
spring: datasource: username: root password: 123456 url: jdbc:mysql://localhost:3306/lianxiTwo driver-class-name: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource initiaSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECE 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true filters: stat,wall,log4j maxPoolPrepareStatementPerConnectionSize: 20 useGlobalDataSourceStat: true connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
controller:
package com.lianxitwo.springbootjdbctwo.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; import java.util.Map; @Controller public class Getjdbc { @Autowired JdbcTemplate jdbcTemplate; @ResponseBody @GetMapping("query") public Map<String, Object> map(){ List<Map<String, Object>> list = jdbcTemplate.queryForList("select * from classOne"); return list.get(0); } }
配置文件:
package com.lianxitwo.springbootjdbctwo.config; import com.alibaba.druid.pool.DruidDataSource; import com.alibaba.druid.support.http.StatViewServlet; import com.alibaba.druid.support.http.WebStatFilter; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import javax.sql.DataSource; import java.lang.reflect.Array; import java.util.Arrays; import java.util.HashMap; import java.util.Map; @Configuration public class DruidConfig { @ConfigurationProperties(prefix = "spring.datasource") @Bean public DataSource dataSource(){ return new DruidDataSource(); } @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); Map<String, String> map = new HashMap<>(); map.put("loginUsername","admin"); map.put("loginPassword","123456"); map.put("allow",""); map.put("deny","14.153.78.101"); bean.setInitParameters(map); return bean; } @Bean public FilterRegistrationBean webStatFilter(){ FilterRegistrationBean bean = new FilterRegistrationBean(); bean.setFilter(new WebStatFilter()); Map<String, String> initParams = new HashMap<>(); initParams.put("exclusions","*.js,*.css,/druid/*"); bean.setInitParameters(initParams); bean.setUrlPatterns(Arrays.asList("/*")); return bean; } }
