Spring Boot集成DruidSQL监控

Spring Boot集成DruidSQL监控

最近在写子查询的时候，发现一个确定的查询却有好几条数据显示，这就很尴尬了，所以我使用Druid来测试了一下，最后发现是自己写错了

获取系统配置

@ConfigurationProperties(prefix = "spring.datasource.druid")public class DruidDataSourceProperties { //jdbc private String driverClassName; private String url; private String username; private String password; //jdbc connection pool private int initialSize; private int minIdle; private int maxActive = 100; private long maxWait; private long timeBetweenEvictionRunsMillis; private long minEvictableIdleTimeMillis; private String validationQuery; private boolean testWhileIdle; private boolean testOnBorrow; private boolean testOnReturn; private boolean poolPreparedStatements; private int maxPoolPreparedStatementPerConnectionSize; //filter private String filters; public String getDriverClassName() { return driverClassName; } public void setDriverClassName(String driverClassName) { this.driverClassName = driverClassName; } public String getUrl() { return url; } public void setUrl(String url) { this.url = url; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public int getInitialSize() { return initialSize; } public void setInitialSize(int initialSize) { this.initialSize = initialSize; } public int getMinIdle() { return minIdle; } public void setMinIdle(int minIdle) { this.minIdle = minIdle; } public int getMaxActive() { return maxActive; } public void setMaxActive(int maxActive) { this.maxActive = maxActive; } public long getMaxWait() { return maxWait; } public void setMaxWait(long maxWait) { this.maxWait = maxWait; } public long getTimeBetweenEvictionRunsMillis() { return timeBetweenEvictionRunsMillis; } public void setTimeBetweenEvictionRunsMillis(long timeBetweenEvictionRunsMillis) { this.timeBetweenEvictionRunsMillis = timeBetweenEvictionRunsMillis; } public long getMinEvictableIdleTimeMillis() { return minEvictableIdleTimeMillis; } public void setMinEvictableIdleTimeMillis(long minEvictableIdleTimeMillis) { this.minEvictableIdleTimeMillis = minEvictableIdleTimeMillis; } public String getValidationQuery() { return validationQuery; } public void setValidationQuery(String validationQuery) { this.validationQuery = validationQuery; } public boolean isTestWhileIdle() { return testWhileIdle; } public void setTestWhileIdle(boolean testWhileIdle) { this.testWhileIdle = testWhileIdle; } public boolean isTestOnBorrow() { return testOnBorrow; } public void setTestOnBorrow(boolean testOnBorrow) { this.testOnBorrow = testOnBorrow; } public boolean isTestOnReturn() { return testOnReturn; } public void setTestOnReturn(boolean testOnReturn) { this.testOnReturn = testOnReturn; } public boolean isPoolPreparedStatements() { return poolPreparedStatements; } public void setPoolPreparedStatements(boolean poolPreparedStatements) { this.poolPreparedStatements = poolPreparedStatements; } public int getMaxPoolPreparedStatementPerConnectionSize() { return maxPoolPreparedStatementPerConnectionSize; } public void setMaxPoolPreparedStatementPerConnectionSize(int maxPoolPreparedStatementPerConnectionSize) { this.maxPoolPreparedStatementPerConnectionSize = maxPoolPreparedStatementPerConnectionSize; } public String getFilters() { return filters; } public void setFilters(String filters) { this.filters = filters; }}

设置数据源
