此处配置SpringMVC的视图解析器，静态资源等，依旧照搬配置文件中的代码
3.PropertyConfig
package com.bdqn.lyrk.ssm.study.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
@Configuration
@PropertySource("classpath:application.properties")
public class PropertyConfig {
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.driver}")
private String driver;
@Value("${spring.datasource.user}")
private String user;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.web.view.prefix}")
private String webViewPrefix;
@Value("${spring.web.view.suffix}")
private String webViewSuffix;
@Value("${spring.web.static.handler}")
private String webStaticHandler;
@Value("${spring.web.static.resource}")
private String webStaticResource;
@Value("${spring.web.static.cache.period}")
private Integer webStaticCachedPeriod;
@Value("${mybatis.type.alias.package}")
private String mybatisTypeAliasPackage;
public String getWebViewPrefix() {
return webViewPrefix;
}
public String getWebViewSuffix() {
return webViewSuffix;
}
public String getWebStaticHandler() {
return webStaticHandler;
}
public String getWebStaticResource() {
return webStaticResource;
}
public Integer getWebStaticCachedPeriod() {
return webStaticCachedPeriod;
}
public String getMybatisTypeAliasPackage() {
return mybatisTypeAliasPackage;
}
public String getUrl() {
return url;
}
public String getDriver() {
return driver;
}
public String getUser() {
return user;
}
public String getPassword() {
return password;
}
@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
此处用于读取application.properties的文件内容 注意@Value与@PropertySource的含义
