Question

我有一个Spring Boot应用程序，它有一些配置属性。我试图为某些组件编写测试，并希望从test.properties文件加载配置属性。我无法让它发挥作用。

这是我的代码：

test.properties文件（在src / test / resources下）：

vehicleSequence.propagationTreeMaxSize=10000

配置属性类：

package com.acme.foo.vehiclesequence.config;

import javax.validation.constraints.NotNull;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = VehicleSequenceConfigurationProperties.PREFIX)
public class VehicleSequenceConfigurationProperties {
    static final String PREFIX = "vehicleSequence";

    @NotNull
    private Integer propagationTreeMaxSize;

    public Integer getPropagationTreeMaxSize() {
        return propagationTreeMaxSize;
    }

    public void setPropagationTreeMaxSize(Integer propagationTreeMaxSize) {
        this.propagationTreeMaxSize = propagationTreeMaxSize;
    }
}

我的测试：

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = VehicleSequenceConfigurationProperties.class)
@TestPropertySource("/test.properties")
public class VehicleSequenceConfigurationPropertiesTest {

    @Autowired
    private VehicleSequenceConfigurationProperties vehicleSequenceConfigurationProperties;

    @Test
    public void checkPropagationTreeMaxSize() {
        assertThat(vehicleSequenceConfigurationProperties.getPropagationTreeMaxSize()).isEqualTo(10000);
    }
}

测试失败，＆＃34;期望实际不为空＆＃34;意味着未设置配置属性类中的属性propagationTreeMaxSize。

发布问题两分钟后，我找到了答案。

我必须使用@EnableConfigurationProperties(VehicleSequenceConfigurationProperties.class)启用配置属性：

@RunWith(SpringRunner.class)
@TestPropertySource("/test.properties")
@EnableConfigurationProperties(VehicleSequenceConfigurationProperties.class)
public class VehicleSequenceConfigurationPropertiesTest {

    @Autowired
    private VehicleSequenceConfigurationProperties vehicleSequenceConfigurationProperties;

    @Test
    public void checkPropagationTreeMaxSize() {
        assertThat(vehicleSequenceConfigurationProperties.getPropagationTreeMaxSize()).isEqualTo(10000);
    }
}

Spring Test中未加载配置属性
